Group A: Haplogroup A.

Group E: Haplogroup E.

Group E: O'Keane sept of Connemara & Co Mayo.

Group G: Haplogroup G. With just one member thus far (although he has kin who have not joined), we await future developments.

Group I2a: Haplogroup I2a, pre-Celtic British and Irish

Group I-L161: Haplogroup I2a2, a Cain/Keane/Quinn group from Kilkee, Co Clare;

Group I2b: Haplogroup I2b, pre-Celtic British and Irish.

Group R-M222 North West Irish Type: O'Cathain of Ciannachta Glinne-geimhein, Co. Derry, a branch of the Northern Ui Niall, descended from King Niall Noigallach. (See "Matching Niall of the Nine Hostages" on the FTDNA home page). This large group, positive for markers P312 and L21, is readily distinguished from other Cain/Kane/Keanes by marker M222+);

Group R-M269: Haplogroup R-M269 "Caucasian" requiring deep clade testing in order to learn more.

Group R-M269: Keanes from the Galway & Roscommon border.

Group R-P312 Cain: An unidentified Cain group with Celtic P312+ DNA;
