Irish DNAAtlas Where Science & Genealogy Meet

Lorna Moloney produces and presents the Genealogy radio show and this airs weekly from wonderful Kilkee at Raidio Corcabaiscinn. Corcabaiscinn is the name for an old tribal region of county Clare. The radio show has over 100 shows podcast and all are available. You can listen to the genealogy radio show which is about The Irish DNA Atlas and is titled: The Irish DNA Atlas - Where Science and Genealogy Meeting. The report is called: The Irish DNA Atlas: Revealing Fine-Scale Population Structure and History within Ireland is authored by Edmund Gilbert, Seamus O’Reilly, Michael Merrigan, Darren McGettigan, Anne M. Molloy, Lawrence C. Brody, Walter Bodmer, Katarzyna Hutnik, Sean Ennis, Daniel J. Lawson, James F. Wilson & Gianpiero L. Cavalleri.

Researchers led by the RCSI (Royal College of Surgeons in Ireland) and the Genealogical Society of Ireland have published 'The Irish DNA Atlas; It has been described as a "landmark study" which is still ongoing and has produced the output of a "genetic map of the island of Ireland, revealing patterns of genetic similarity". 10 identifiable clusters have been noted and they adhere to the ancient Overkingdoms in Ireland.

196 Irish individuals with four generations of ancestry linked to specific areas across the island of Ireland provided DNA. Further comparative analysis with DNA from Britain and Europe show geographic clusters within Ireland. 10 in total, 7 Gaelic Irish, 3 British-Irish.

Edmund Gilbert (RCSI) tells us that “Our work informs on Irish history; we have demonstrated that the structure emerging from genetic similarity within Ireland, mirrors historical kingdoms of Ireland".

National Geographic interestingly noted in "FROM THE WEB "One big finding was the distribution of people prone to complex genetic disorders. In both the United Kingdom and Ireland, for example, prevalence of multiple sclerosis increases the farther north you go. And compared with the rest of Europe, the Irish have higher rates of cystic fibrosis, celiac disease, and galactosemia, a serious metabolic disorder that prevents the breakdown of sugars in dairy, legumes, and organ meats"

Michael Merrigan (GSI), co-author on the paper, stated “for those interested in genealogy and Irish history, this study challenges many of our received narratives on the origins of the people of Ireland". According to Merrigan, "new and very exciting research opportunities for many disciplines emerge, especially, those researching the Irish medieval genealogies and the history of Irish clans/septs.” This is a very important study as Irish medieval genealogies inform us as to surnames, political lineages, networks and lordships from the 11th to the 17th century. The radio show today looked at some of the earlier Kingdoms and the Dalcassian and Eoghanacht origins mentioned in the report.

The study design depended on 8 great-grandparents who had been born within 50km of each other. This would be two generations removed and the following table can give you an idea of what period in Irish history this could represent ancestry, so this would be people who had ancestry coming the one locale in the latter half of the nineteenth century. As the Great Famine occurred from 1845, this must have posed problems for sample collection in various parts of the country.

The tree by waitbutwhy also shows how many great-great-great-great-great Grandparents we have, 128 in a relatively short space of time. This is where what we need to remember when we are looking at DNA results and our matches,

As Ireland is known for emigration, this was not an easy thing to achieve. It is clearly noted that while they "are delighted by what the study to date has revealed, this is a live study; the more people who participate the greater resolution we can achieve."

Our show today looked at The Eoghanacht and The Dalcassian Clans. There were Munster based. According to Rev. Woulfe, "EOGHANACHT, race of Eoghan Mor, son of Oilioll Olum, King of Munster in the 3rd century, which was sub-divided into Eoghanacht Chaisil, Eoghanacht Locha Lein, Eoghanacht Aine, &c., and to which belonged the chief families of South Munster". The Eoghanacht Chaisil could be located "in the barony of Middlethird, Co. Tipperary". The Éoganacht were a group of tribes claiming a common lineage and spread throughout Munster. They were noted as kings of Munster from an early period until the rise of the Dal gCais in the 10th century. The main sub-tribes in the region of the barony were and please note baronies did not become a territorial division until the sixteenth and seventeenth century.

Eóghanacht & Dalcassians

  • Eóghanacht Chaisil (Cashel). Septs included O'Callaghan, MacCarthy, MacGillycuddy, MacAuliffe, O'Sullivan.
  • Éoganacht Beag Chaisil (Eoganacht Caille na Manach, in the barony of Kilnamanagh)
  • Éoganacht Mhór Muman (about Knockgraffon, in the barony of Middle Third)
  • Eóghanacht Airthir Chliach (Tipperary town district)
  • Eóghanacht Durluis (in or near Thurles, in the barony of Eliogarty)

The Dalcassians: According to Connellan, the chief families of this sept were Lysacht, MacArthur, MacBruodin, MacClancy, MacConry, MacCurtin, MacDonnell, MacEniry, MacGrath, MacMahon, MacNamara, O'Ahern, O'Brien, O'Brody, O'Casey, O'Cashin, O'Considine, O'Davoran, O'Dea, O'Duhig, O'Grady, O'Hanraghan, O'Hartigan, O'Hea, O'Healy (modernized Haley and Hayley), O'Heap, O'Heffernan, O'Hehir, O'Hickey, O'Hogan, O'Hurly (modernized Hurley), O'Kearney, O'Kennedy, O'Liddy, O'Lonergan, O'Meara, O'Molony, O'Noonan (or O'Nunan), O'Quinn, O'Shanahan (or O'Shannon), O'Sheehan, O'Slattery, O'Spillane, O'Twomey, etc.

The following were also of the Dalcassian race: the families of MacCoghlan, chiefs in the King's County; O'Finnelan (or O'Fenelon), and O'Skully, chiefs in Teffia, or Westmeath.

As we are always clear on our sources for the blog resources and the genealogy radio show, we would like to give 5***** to Library Ireland which is a free resource. The LibraryIreland.com project was commenced in February 2005 with the aim of providing free information on all aspects of Ireland — antiquities, biography, folklore, genealogy, history, names, social history, and much more besides.

The wealth of Irish texts is constantly growing, so a sitemap has been added to aid navigation, although this is restricted through necessity to the main architecture of the site, and it is therefore worth making use of the search facility to find what lies buried deep in the heart of Library Ireland. It is hoped that the material provided online will stimulate further interest and research, and consequently help in the preservation of the country's rich historical heritage.

It is also intended that the site will inspire a revival of interest in collecting old books on Ireland, a gentle pastime that seems to have greatly diminished recently. We need a fresh awareness of the delight of owning the actual book, an appreciation that it is more than its contents. Indeed, it can be an art form in itself. In the surroundings within which we move every day, few things are more pleasant to encounter than a bookcase of attractive bindings to catch the eye and fill us with a sense of history and provide a link with the past.

Library Ireland can be contacted at info@libraryireland.com, but please be aware that because of time and resource constraints they are unable to answer genealogical and other enquiries which involve any degree of research. If you make an enquiry and do not receive a response then please accept their apologies, but it will be because we cannot provide an adequate or easy answer. Finally, please enjoy browsing Library Ireland, and don't forget to visit us again.
