Corca Laidhe was a first millennium kingdom in the southern part of Ireland (Munster). Some scholars give an approximate date of 200 C.E. as an estimate of Corca Laidhe's presence in Munster. The acknowledged rulers were the O'Driscolls.
Corca Laidhe had a close affinity with Ossory, another old Irish kingdom that covered most of County Kilkenny and part of County Laois. Ossory was the origin of St. Kieran's father. The diocese of the same name, roughly coterminous geographically with the region, was founded with St. Kieran's mission, though its boundaries were not formally set down until much later. The Corca Laidhe, which had control of Munster, briefly had control of Ossory around the time of St. Kieran.
As a related line of research, the project administrators have an interest in identifying Corca Laidhe surnames that also appear in historical records of Kilkenny.
Encroachment of the O'Mahonys and various Eoghanacht septs by mid-to-late first millennium, the arrival of the Anglo-Normans around 1150 C.E., and conflict with England all contributed to the demise of the Corca Laidhe and eventually confined the descendants of the inhabitants and former rulers into a territory coinciding with part of the Roman Catholic Diocese of Ross - roughly Skibbereen to Clonakilty. This part (see illustration below) was split from the Beara part of the diocese, the latter now part of the Diocese of Kerry. The reconfiguration of Ross was likely due to the aforementioned pressures.
The O'Driscolls lost their ruler status and became McCarthy vassals. 19th century scholars attempted to track down the chieftain line. They interviewed some of the local people in west Cork, but were unable to conclusively trace any possible surviving direct male line descendants of Finghin O'Driscoll (17th century). There is no known surviving blood chieftain line, though possible cadet branches are still being investigated.
There is documentation of the names of the hereditary proprietors (chieftains) of Corca Laidhe, relatives, and their subjects from the 12th century. Corca Laidhe Pedigree (below) describes some of the texts used to reconstruct the family histories.

Corca Laidhe Territory
The Corca Laidhe people ended up somewhat confined to the boundaries of the old Catholic Diocese of Ross, comprised of parts of the present day districts of Skull, Skibbereen, and Clonakilty in West Cork. The illustration shows the portion of the diocese along the Skibbereen to Clonakilty coastline. Relevant R.C. Parishes include Aughadown, Rath & Islands, Skibbereen, Castlehaven & Myross, Kilmacabea & Kilfaughnabeg, Rosscarbery & Lissavaird, Kilmeen & Castleventry, Clonakilty & Darrara, Ardfield & Rathbarry, Timoleague & Clogagh, and Barryroe (Lislee, Abbeymahon, Donoughmore).
Corca Laidhe Pedigree
Old historical texts covering the Corca Laidhe people 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.
An additional piece of documentation has been added to our resources: Corcu Loígde: Land and Families, a paper by Dr. Donnchadh Ó Corráin of UCC.
Our Overview (About Us) page lists the project requirements and our FAQ page discusses those requirements in detail. Prospective members need to submit the required research participation permission in the JOIN window when they click JOIN.
Project members are encouraged to use the Activity Feed to ask questions about and discuss Corca Laidhe genealogy, history and DNA. 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. Rootsweb support has been unreliable over the past several years. We don't know when the list archives will be uploaded.

- 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.

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."
