What's in a name? Or 'The Art of Interpreting the Science of Y-DNA'

Y-DNA testing offers researchers a tantalising window into the past without the transitory limitations of autosomal testing. Y-DNA opens up the possibility of tracing your direct male lineal descent as far back as chromosomal Adam. (1) Y-DNA also has decided advantages over the mitichondrial testing (MT-DNA), the female equivalent: unlike MT-DNA, Y-DNA material provides regular mutation rates allowing more accurate dating estimates. (2) Combined with forensic archeology it is possible to trace your direct male lines migratory history helping to fill out the ancient narrative. (3) Again, in this article I'm going to be using my own results to illustrate my points for reasons of both convenience and familiarity.

A haplogroup is a genetic population that share a common ancestor with a specific Single-Nucleotide Polymorphism mutation (SNP). (4) My own personal trail of polymorphisms from R-M269 which is the most common chromosomal lineage for European men, itself descending in the distant past from Chromosomal Adam in Africa is as following: R-P311/S116, ZZ290, L21/S145, DF13, ZZ10_1, CTS3386, S19268, FGC13300, S9797, BY42759, BY43560. (5) The technology has a second trick up its sleeve: Short Tandem Repeat (STR) marker testing is used to fill in the gaps between SNPs and is more suited to interpreting more ‘recent’ ancestry within the last several hundred years. The more remote the Most Recent Common Ancestor between two kits, the more markers in common are dropped. (6)

Using my SNP results we can extrapolate that direct male ancestor, a ‘proto-Celt’ from the Atlantic coast of the continent, belonging to either the haplogroup R-DF13 or its immediate downstream successor R-ZZ10_1, arrived in what would later be known as England around 2500 BCE (Before Common Era). Over the next thousand years his direct descendants moved steadily Northwards before a male - likely of the haplogroup R-CTS3386 - migrated to what we know now as Ireland around 1400 BCE. Four bodies interred in the burial ground at The Bishop’s Seat, Kilteasheen, County Roscommon, Connacht Province, which was in use between 600 to 1300 CE (Common Era), descend from the R-ZZ10_1 line; this indicates a shared ancestor born around 2500 BCE. However, another body, ‘Kilteasheen34’ belongs to haplogroup BY42759 and therefore shares a much more recent common ancestor born around 200 CE. Additionally drawing on STR matching, I matched only one kit at the 111 marker level (out of a total database of close to 600, 000) and he also has the surname MALLETT. The specific test results (only 8 STRs dropped from 111) and subsequent exchange of genealogical research has suggested that we may have shared an ancestor that lived within the last 10-15 generations (estimated to have been born between 1450 and 1700 CE). (7) Therefore by scientifically merging the genetic fate with the forensic archaeology enables a basic narrative of direct descent to be constructed.

Chart of  descent from Haplogroup R-BY42759 prepared by Colin Woollcott Mallett

Based on analysis provided by the R1b-CTS3386 and Subclades Project, FTDNA, 2019. (iii)

In a sense, a haplogroup is a 'genetic surname' for men, one that evades the vagaries of fate. I would argue that we can fill out more of the wider 'family' story through analysis of the etymology and geographical association of the surnames held by those tested. Looking above at a chart (figure iii) of the specific descendants of my own (penultimate) terminal haplogroup R-BY42759, its immediately noticable that several surnames are repeated, specifically FERGUSON, CARROLL and MILBURN.  There are in fact three CARROLL and three FERGUSON descendants. One of the FERGUSON lines is separated from the other two by a divergence estimated to have occurred around 1050 CE!  Equally, one of the surnames for instance on that arm of the chart belongs to a JAMES (which is not a particularly Celtic surname at all!) sharing a node with the third FERGUSON as late as 1800 CE. This is a reminder that when we study a chart of haplogroup descent, each line is labelled with a surname endpoint. But what this chart does suggest to me is that select lines descending from BY42759 have either settled or remained in a specific region (or regions in Ireland and Scotland) where either of those two surnames, CARROLL and FERGUSON, are common. (8)

The surname CARROLL was first associated with the Kingdom of Oriel (situated within the modern counties of Louth and Monaghan) and later became common in County Offaly. In fact CARROLL is one of the twenty five most common surname in Ireland (9)

Meanwhile, the FERGUSON clan is closely associated with Ayrshire, Scotland. (10) From the Third Century CE, the 'Scoti' migrated from Ireland to 'Caledonia'. By approximately 500 CE, they were well established in Dalriada (comprising of Argyllshire and the islands of Jura, Islay and Iona). Clan FERGUS(S)ON claims descent from King Fergus mor McErc who it is believed established the Scottish monarchy. (11)

In fact, according to the ancient genealogies of Ireland, King Fergus himself was said to be a descendant of King Niall of the Nine Hostages, the 128th High King of Ireland, in turn descended from 110th High King of Ireland Conn of the Hundred Battles, himself a descendant of King Heremon, who along with his brother King Heber were said to be the first of the Milesian Kings of Ireland. (12) There is a theory that the Royal haplogroup is R-M222 and a staggering 21.5% of the male population in North Western Ireland are said to share this genetic fingerprint. (13) The haplogroup's descendants are most common in the North of Ireland and possessed laregly by those with surnames closely associated with the Neill clan including DOHERTY, GALLAGHER, O'REILLY and QUINN. (14) The estimation of the age of the R-M222 mutation does approximately allign with the period of his rule which began in 379 CE. (15) But it must be kept in mind that even High King Niall is a 'quasi-hisorical' figure, although the Y-DNA evidence is highly suggestive of a most fecund shared ancestor for that haplogroup's descendants (16). My own terminal haplogroup, like R-M222, is a subclade of R-DF13 but our last direct common ancestor then lived about 2500 BCE — so even if there were still a High King of Ireland, I doubt any of us of haplogroup R-BY42759 and below would be candidates! (17)

Returning to the R-BY42759 chart (figure iii), the descendants of the node estimated to have occurred around 500 CE appear to have experienced some kind of cultural shift, in that they share what could be described as more Anglo-Norman surnames: ROBBINS, VANCE, MILBURN and MALLETT. This would suggest a downstream exposure to a Norman influence over several generations perhaps as a result of their invasion of Ireland from 1169 CE or perhaps migration to Normanised England or Scotland. As discussed in a previous article, MALLETT (originally MALET) is either a Norman or Norman inspired surname. (18) ROBBINS is derived from the personal name Robert introduced by the Normans. (19) The surname VANCE is thought to be a modernised version of the Norman de VAUX. (20) MILBURN is in fact a notorious Border Reiver surname. (21) It is known that some members of the descendant haplogroup R-S11304 took the surnames THOMPSON and CLARK. (22)  All these clues point to several lines descending from the 500 CE node sharing common experiences of either assimilation with and/or migration into the 'Anglosphere', which matches the narrative suggested by the migratory charts provided at the begining and brings us full circle. 

In conclusion, Y-DNA is a happy accident of evolution. It's a technology that opens a unique, inadvertant window into the past. Like all DNA technologies, Y-DNA testing requires careful interpretation of results but its generally more revealing than studies of MT-DNA thanks to a faster mutation rate. Attention to endpoint surnames, specifically their etymology and geographical associations I think can be a valuable technique to help develop a richer, more expansive narrative. Taking into consideration the migatory pathways demonstrated by my sibling lines the FERGUS(S)ON clan and the MILBURN family that both had an association with Ayrshire, it's possible that my own ancestral patrilenial migration story may vary from that depicted in figure ii. Our specific journey may have also involved a geographic reversal of direction from Ireland, back through Scotland, then gradually southwards through the English midlands (wherein one line of the MALLETT family established themselves in Warwickshire) and then westwards to eventually settle in Cornwall.

(1) Until recently, Chromosonal Adam was considered to be the most recent common male ancestor of all modern humans, Y-DNA in the form of a Y-Chromosome being passed down from fathers to sons, mutating at a fairly constant rate of around every 125 years or perhaps around 3-4 generations. Chromosomal Eve is the female equivalent but her MT-DNA is passed on to both male and female children. Its unlikely they coexisted but were both members of larger populations.

(2) MT-DNA haplogroup mutation rate is thought to be 4.6 times slower than that found in Y-DNA. This can make it difficult to estimate if a MRCA shared by two kits sits within a useful genealogical timeframe. It is useful though in establishing if two people do or do not share a direct maternal line of descent. See: Charles F.

(8)  According to tradition, both of these families were meant to descend from the two sons of King Milesius who landed in Ireland around 1699 BCE: the CARROLLs descending from the eldest son Heber and the FERGUSONs (the Anglicised version of McFERGUS) descending from the younger son Heremon. In the case of the men descending from BY42759 this clearly can't be the case as according to the said chart all these CARROLLs and FERGUSONs share an ancestor who lived as recently as around 1000 CE. See: Author Unknown, 'Ancient Origins of Ireland', House of Names, n.d., https://www.houseofnames.com/blogs/Ancient-Origins-of-Ireland , accessed 13 February 2025; John Rooney, 'The Carroll Family' (from A Genealogical History of Irish Families with their Crests and Armorial Bearings, 1895), Library Ireland, n.d., https://www.libraryireland.com/irish-families/carroll.php , accessed 13 February 2025; John Rooney, 'The McFergus or Ferguson Family' (from A Genealogical History of Irish Families with their Crests and Armorial Bearings, 1895), Library Ireland, n.d.,  https://www.libraryireland.com/irish-families/mcfergus.php , accessed 13 February 2025.

From Natives to Normans to Protestants: Irish surnames from the Ninth Century to the present day

A Celtic cross at St. David's Church, Naas, County Kildare,

I recently made a close study of the surnames of Ireland. The starting point of my enquiries was John O'Donovan's seminal series 'Origin and Meanings of Irish Family Names' published in seven instalments in the Irish Penny Journal in 1841. Donovan (1806-1886) was an Irish literary scholar of great acclaim. I also consulted Irish Names and Surnames by Patrick Woulf (1872-1933) published in 1922. While sometimes contested by his successors, Father Woulfe's book remains a foundation stone of scholarship on the topic. Inevitably, I also turned to the voluminous works of Edward MacLysaght (1887-1986), a very famous Irish genealogist and scholar. While I undertook this work mostly to gain a better understanding of my own considerable Celtic heritage, there are specific research questions I sought to answer. How were Irish surnames formed? In what ways and why did they change over time? And lastly, using what I learned from my research to seek an answer to a personal enquiry: how did a Cornish family of Irish descent end up with a Norman surname (?!).

Ireland was in fact one of the earliest regions in the western world to develop a system of surnames. (1) There is a myth that surnames were established by King Brian Boru. (2) However, there is evidence of the use of surnames in what became Ireland by the later part of the first millennium, long before his reign. (3) These surnames were formed of course in the native language: Gaeilge. The earliest surnames were initially formed from the father's name prefixed with "Mc/Mac" (for father) or "O' " (for a patrilineal ancestor). (4) The rarer equivalent prefix for a specifically female descendant was "ni". (5) The words "giolla" and "maol" were eventually introduced as prefixes to denote a follower or servant, normally of a Saint. (6) Gradually surnames in Ireland expanded to incorporate occupations and personal characteristics. (7) It is rarer to encounter Gaelic Irish surnames based on a place of habitation. (8)

Most of these early Gaelic surnames were originally transitory, rather than hereditary, in nature. (9) Overtime though, the Irish, like the Welsh, adopted the practice of developing names that represented a 'veritable genealogy'. MacLysaght explained:

John MacMahon MacWilliam MacOwen MacShane was, of course, John MacMahon whose father's Christian name was William and his great grandfather's was Shane.

I'm not exactly sure then what MacLysaght would have made of Donal McShane Mallacht O'Neill of Shagrom in the Parish of Dungannon, County Tyrone who was a native granted land in 1610. His son's subsequent full name was constituted as Eugene McDonal McShane Mallacht O'Neill - a title that includes a personal name, father's name, grandfather's name, nickname (?) and clan name (?!). This all seems to imply that the practice was flexible or more complex than MacLysaght argued—the custom possibly prone to regional variation. (10) Indeed, Donal is listed under the surname 'Mallett' in David Donson's The People of Ireland 1600-1699! (11) The 1659 census, a primary source relied on by scholars for studies in this period, likely suffered from misinterpretation of that practice. (12)

To understand the development of surnames in Ireland it is necessary to understand its history of invasions and immigration. Vikings settled in Ireland during the Ninth Century and built the first real city states of the region in Dublin, Wexford, Waterford, Cork and Limerick. The Norse proved to be valued traders and an economic interdependence developed between their cities and the native Irish that helped to ensure their survival as much as the decline of the influence of the High Kingship. (13) The surname Doyle is thought to have derived from the Gaelic expression "dubh-ghall" meaning "dark foreigner". There is a strong belief that because O'Dubghaill cannot be found in the great Gaelic genealogies their eponymous ancestor was likely a Norseman. It is also mostly found in coastal counties where Norse settlements were located. (14) Many Norse given names were transformed into Irish surnames including O'Rourke or Groarke ("descendant of Rurarc") and O'Loughlin ("descendant of Lochlann"). (15)

The first true upheaval affecting surnames in Ireland was inflicted by the Normans from the late 12th Century. The system of patrilineal prefixes had become firmly established for at least a century before the arrival of the Normans. (16) One of the lasting legacies of the Norman invasion of Ireland was a large sub-set of Hiberno-Norman surnames. (17) For instance, the Normans introduced the enduring prefix "Fitz" to Ireland. (18) The murder of William de Burge, the third Earl of Ulster, in 1333 led to a weakening of English control and an increase in this "Hibernicization" of surnames particularly in the Kingdoms of Connaught and Munster. As O'Donovan insists, it is misleading to refer to the invaders and their descendants as 'English' considering the fact that their ancestors had "dwelt scarcely a century in England." Typically for Normans, they appear to have assimilated rather than conformed outright with the native population. Instead of simply taking Gaelic or Norse names, the local Normans reacted by adding the prefix "Mac" to the name of a personal ancestor. (19) This was one aspect of the Normans becoming "Hiberniores Hibernicis ipsis" or "more Irish than the Irish themselves"! (20)

English initiatives designed to prevent the settlers from 'going native' arguably inadvertently impacted the nomenclature of Ireland. The Statutes of Kilkenny passed in 1367 were designed to define the "cultural, racial and political identity of the declining English colony in Ireland." (21) One of these statutes specifically made it illegal for the English settlers and their descendants to adopt Gaelic surnames. (22) This edict was limited to the Irish 'Irish of the Pale' which consisted of Dublin, Meath, Louth and Kildare. (23)

A subsequent law passed in 1465 made it mandatory for every Irishman in the Pale to adopt an 'English' surname. While the genteel classes resisted, the lower orders in Dublin and Leinster complied. (24) Together, these laws may have ensured that many Norman surnames persisted despite a high degree of assimilation. The perseverance of Norman surnames led to surnames such as Burke, FitzGerald and Keating becoming indistinguishable from those of more traditional Gaelic origin such as O'Connor. (25)

The second upheaval of Irish nomenclature was instigated by the English during the plantation period beginning in the mid-15th Century. The Elizabethan 'settlers' and their descendants were never 'Hibernicized' as the Normans had been. (26) Inversely, throughout the Seventeenth Century, the prefixes "Mc" or "Mac" and "O' " were abandoned by the native population, reflecting an inclination by many to bury their Irishness in the wake of the second conquest. (27) Therefore, many of the surnames of Ulster which possess the "Mc" and "Mac" prefixes are descended from Seventeenth Century Scottish planters. (28) Many Irish surnames over the centuries then were gradually anglicised. (29) MacLysaght somewhat sniffily asserts that the "mutilation and corruption of Irish surnames took place in the seventeenth and to a lesser extent the eighteenth centuries." (30) This corruption sometimes took the form of adopting an English pronunciation of a Gaelic name. (31) O'Donovan lamented that many Gaelic surnames were translated "erroneously" and on the basis of "fancied resemblance in the sounds of both" as opposed to shared meaning. (32) The more genteel native classes favoured a shift to French and Spanish surnames. (33) John O'Donovan in the sixth instalment of his aforementioned 1841 series, related how a descendant of the ancient O'Malley family of County Mayo changed his surname to de Maillet. He rather unkindly observed:

...though his friends condescend sometimes to call him by this name, they can scarcely refrain from laughter while pronouncing it, for they know very well that he descends from Owen O'Malley, the father of the famous heroine Grania Wael, and chief of Umaillia or the Owles, in the reign of Queen Elizabeth.

There were likely many other instances of this kind of adaptation, however clusmy, across all classes. (34) This widespread aversion by the Irish to their Gaelic roots was not reversed until the later 19th Century through the work and encouragement of the Gaelic League. (35)

The revocation of the 'Edict of Nantes' accelerated Huguenot migration to Ireland. Even so, 'An Act to Encourage the Migration of Protestant Strangers' had already been passed more than twenty years earlier in 1662, reflecting their perceived value to the local economy as "merchants, manufacturers and bankers". (36) The great Huguenot migration of the Seventeenth Century introduced many new surnames. (37). The same was true with the migration of several hundred German Palatine families to Ireland in the early Eighteenth Century and the majority settled in County Limerick. (38) Regardless, the transplantation of surnames from England and elsewhere to Ireland was sometimes gentle and gradual. Many Anglo-Irish surnames for instance were likely introduced by small waves of migrants during the Medieval period. (39)

MacLysaght despaired of the inability to distinguish between identical names that are common in both Ireland and England such as Collins, Boyle and Smith. (40) While Mallett (and its variations Malet and Mallet) is a surname more common to England than Ireland, it is also found in both countries. Thankfully by combining DNA testing with archival research, it is now possible to be more certain of your 'deep ancestry', on the direct male line at any rate. Archaeogenetics has confirmed that my own patrilineal line may have arrived from what would be Scotland to Ireland around 1400 BCE and resided there as late as 1300 CE, perhaps even longer, before migrating to England. The most recent common ancestor shared with my highest-level Y-DNA match, who also incidentally shares my surname, probably lived somewhere between 1300 and 1500 CE. Our most recently traced ancestors were respectively born in Cornwall and Warwickshire, both around 1800 CE. (41) Indeed, UK taxation records from 1440 reveal that an Irishman named Tago Malet was living in Newton Ferrers, Devonshire! For all we know he could have been our family's eponymous ancestor! (42) Therefore, assuming my surname was adopted by an ancetsor in Ireland and not some kind of cultural camouflage or inadvertent adoption post-migration to England, it may have been derived because of one of three basic scenarios:

1. By virtue of Normans invading Ireland from the late 12th Century.

2. Through subsequent anglicisation of specific Gaelic surnames.

3. As a result of later immigration, including the mass arrival of Huguenots after 1685.

The Norman surname Malet (and its subsequent variations) transplanted from Normandy and Brittany to the British Isels was Old French in origin and likely traced back to three separate Latin words. (43) John O'Hart in his Irish Pedigrees suggested that the surname Malet - in its primordial form and in Ireland - may have been one of the anglicised forms of the Gaelic surname O'Maoilraite. (44) The surname is listed in the poem titled "Many a branch of the race of Conn" by Giolla Iosa Mor MacFirbis written sometime before 1417. The poem references an O'Ma(o)ilraite whose lands were situated near Errew in the parish of Ballyhean, County Mayo. A long topographical poem, it lists all the land-owning families of Tir Fhiachrach and eulogises each clan head - although the spelling is erratic! (45) According to Father Woulfe, the prefix "Maol" originally meant "bald" or more specifically "tonsured" or shaven like a monk and took on the meaning of servant or devotee when connected with the name of a Saint; therefore "Maol Eoin" was a servant of John. But he also cautioned that it had become confused with the prefix "Mal" taken from the old Celtic word "Maglos" meaning a Chief. This was often used in a variety of ways with nouns, proper or not and even adjectives. Therefore "Maolcaoin" would translate as "Gentle Chief". (46) John O'Hart lists accompanying anglicisations of O'Maoilraite or O'Mailraite as Mulratty, Rattan and Raite. (47) I cannot ascertain the meaning of the Gaelic suffix "raite" but it could be a past participle of "abair" meaning to proclaim, declare or simply to disclose. (48) The poem refers to O'Ma(o)ilraite and his lands in the following manner:

Cul Daingin and Braenros ban,

Oiremh and the enture Imairi

Belong to O'Mailraite, hospitable to the man,

To Whom the literati and the feast were pleasing. (49)

It may be significant that the Scottish Gaelic word "rait" was used to refer to a hill fort and was derived from an earlier Picto-Celtic word "rath" which referred to a defensive structure. (50) The original meaning of O'Ma(o)ilraite is probably lost forever but it may be hidden in some combination of two of the four Gaelic words for 'servant'/'chief' and 'speaker'/'fort'. (51)

Malet is listed by O'Hart in his second volume of Irish Pedigrees as a Huguenot surname in Ireland - although it is noted that one arrived before the rule of Louis XIV began in 1643. (52). Following the mass Huguenot migration to Ireland, the surname Malet had become associated with the French Quarter of the city of Cork. (53) Furthermore, the family of the famous engineer and seismologist, Robert Mallet (1810-1881), began arriving as part of a chain migration from North Tawton, Devonshire to Dublin in the late Eighteenth Century. This family was descended from the illustrious Somerset family with links back to 1066 and all that. Furthermore, adding to the complexity, the first to arrive, Robert's Uncle and namesake, married a woman of alleged Huguenot ancestry making his descendants potentially both of Huguenot and Norman descent! (54)

While it is a more obscure, niche area of study, much has been written and published on the history of surnames in Ireland over the centuries. Following the initial innovation of the custom, the three greatest periods of adaption took place during the Norman Invasion, the Plantation period and the mass Protestant migrations of the Seventeenth and Eighteenth Centuries. The first period saw the introduction of a new set of surnames that persist to the current day. The second period saw an upsurge in English surnames and the subsequent anglicization of the surviving Gaelic ones. The third period by virtue of mass migration, saw an influx of both French and other European surnames. No mastery of Irish Gaelic is required to comprehend the basic linguistic mechanics of the practices determining surnames in Ireland from the Ninth Century; however, the erratic translation of Gaelic surnames to phonetically similar English and European surnames makes tracing their individual history a task best left to the professional linguist. On a personal level and despite my best efforts, it is not yet possible to be certain of the exact origin of my own surname or even to finally conclude that it was in fact adopted during the twilight of my ancestors' ten to twenty centuries in Ireland. But if it was, then it likely occurred because of one of the three scenarios outlined.

In contrast, the translations of O'Heany or Mac Eneany to Bird are examples of erroneous attempts to translate on the basis of meaning despite there being no etymological connection between either surname; the mistranslations are solely based on their shared incorporation of the Gaelic word for 'Bird': ean.

It may be significant that while descendants of my penultimate subclade haplogroup R-BY42759 share predominately Celtic surnames such as Collins, Ferguson and Carroll, my own downstream terminal haplogroup R-BY43560 (and its own successor R-S11304) is characterised by descendants with Norman flavoured surnames: Robbins, Vance and Milburn. Although R-BY43560 diverged from its predecessor as early as 250 CE, this shift in surnames could be evidence of a subsequent cultural upheaval among a specific subset of descendants of R-BY42759.
