Hi All,
My name is Sean O'Neill and I am the administrator of the O'Neill DNA project on FamilyTreeDNA.com
Please see the feed : https://www.familytreedna.com/groups/oneill/activity-feed
My Dad also did the genealogy of all the main branches of the in the book the Ancient and Royal Family of O'Neill. ( this is out of print ).
The O'Neill's were the last great defenders of the Gaelic Tradition in Ireland and with the defeat of Hugh O'Neill at the Battle of Kinsale in 1601, resulted in the plantation of Ulster. Ulster is nine countries and six of these counties make up Norther Ireland today. Cormwell also had a major impact on Ireland in the mid 1650's.
There are three main branches of the family : Tyrone O'Neill's based in Tyrone and the the senior branch, the Clanaboy O'Neill's based in Antrim (and formed around 1200) and the Fews O'Neill's based in Armagh and is a sub branch of the Tyrone O'Neill's formed in 1420 by Aodh O'Neill. There are other septs of O'Neill's around Ireland including the O'Neill's Leinster. The O'Neill's in Cork can be connected to the O'Neill's of Ulster.
The O'Neill's of the Fews lost their lands in Armagh 1650's and ended up in Mayo.
There is also Lord O'Neill who is a Clanaboy O'Neill through the marriage of his ancestor to an O'Neill and has been very active in preserving the O'Neill tradition in Ireland. His family were heavily involved in the politics in Northern Ireland.
Concerning religion, the family is a Catholic family, however, it is not unheard of for families to change religion to retain land. Families have also changed names for various reasons. So, McShane, Johnson and Payne are all names with O'Neill backgrounds.
In the situation described above where there is really no reliable link to Ireland, a DNA test is worth considering. The sample set for O'Neill's now exceeds 600 samples and it is possible to identify the family branch from the test and possibly the location. You need a male O'Neill with a direct know line to your oldest known ancestor to take the test - Ideally a Y-111 and Big Y 700 tests. Unfortunately, these are expensive.
Regards,
Sean.
