Corca Laidhe Pedigree
The Corca Laidhe were a medieval clan in the south west of Ireland. The documents regarding the clan are not always self consistent and/or complete. The material has proven to be difficult to organize into a diagram and it is easy to get confused with so many names being the same from one generation to another or the same name being spelled slightly different. The diagram shows via gray lines some alternate pedigrees that can be picked out of the documents. Nevertheless, no matter the interpretation the general conclusion is the same, i.e. there once was and maybe now are persons named Driscoll, Coffey, Flynn, Leary, Barry and Clancy who share a common ancestor circa 200 AD.
Many families of the Corca Laidhe are referred to as hereditary proprietors. According to Webster's dictionary a proprietor is a person who has the legal right or exclusive title to something. In the present context that something would be land and the attendant income. A hereditary proprietor could originate as a cadet line (2d son, 3rd son, etc.), a son-in-law or reward for loyalty or service rendered. In some cases the listing of proprietors may simply be a record of land owners. There is good reason to expect the Corca Laidhe genealogy to involve multiple haplogroups and clades.
The genealogy of the Corca Laidhe is described by John O'Donovan in his treatise published in 1849 by the Celtic Society in the book Miscellany of the Celtic Society. He described his treatise as "various readings" from the Book of Ballymote as compared with the Book of Lecan, two books complied about 1400 from various other manuscripts. In addition a transcribed copy of the book is available thanks to a project at the University College Cork know as CELT, the Corpus of Electronic Texts. Another important source is the Book of Glendalough, otherwise known as Genealogies from Rawlinson B 502, which dates from 1130; therein one finds the Genelach Sil Lugdach Meic Itha. An O'Leary pedigree can be found in The O'Clery Book of Genealogies written in the 1600s. These books are all online, click the titles.
One purpose of this project is to build a database for names found in O'Donovan's treatise on the Corca Laidhe. Another is to critically examine the genealogy in light of the resultant data. Lastly, the data is made available to other investigators and family historians for analysis as may suit their purpose.

Project members are encouraged to use the Activity Feed to ask questions about and discuss Corca Laidhe genealogy, history and DNA. Until FTDNA implements email notification of Activity Feed posts, please be aware the admins may not know you have posted. Feel free to help one another to assist the volunteer admins.
Additionally there is a Rootsweb mailing list that is open to anyone, whether or not they are in the project. Most project participants have not signed up to it, so a post on the Activity Feed will potentially reach more viewers and responders.

- Irish Ancestors
- Variants - a surname search at the Irish Ancestors site returns info on where a particular variant will be found and a synopsis from the book by Seán de Bhulbh, Sloinnte na hÉireann-Irish Surnames, Comharchumann Íde Naofa, 1997. An acceptable variant is difficult to define. Herein if a variant is acceptable if there is precedent for that name having evolved from the root name and the name is associated with county Cork (or at least numerous and not uniquely connected to some other locale).
- What's In A Name by Nora Hickey
- Agnomen - often in a locality there would be so many persons of a given surname that a secondary name was added to distinguish one family from another and it evolved to a primary name.
- MacLysaght, The Surnames of Ireland, Irish Academic Press, 1985
- O'Hart, Irish Pedigrees (1892), p. 281
- The MacNicaill are said to branch off the Coffey 32 generations subsequent to Lughaidh Maccon leading to the modern names of MacNichol, MacNicol, Nicholls, Nicholas, MacNicholas, Nicholson, Nicolson, Nicols, Nicson, and Nixon. As of 27 Mar 2016, those in the Nichols DNA project who trace to Ireland are overwhelmingly from the north and probably not Corca Laidhe.

Note from member Irwin: "Kirby (O Ciarmaic), Kerwick (O Ciarmaic) and Irwin (O Ciarmacain) derive their surname from the same source and trace their name origin to Knockainy, Limerick and as such monopolized the chieftaincy of Eoghanacht Ainy for centuries. I have no idea of who the known modern-day descendants of Clann-Ciarmhaic are and nor do I know their present-day surnames... According to ... (Big Y) I am closely related to both Driscolls and Finns."
