The O’Neill’s of Dál gCais: R1b1a2a1a1b4h By M.O’Neill

 I have taken sometime to see and find the various origins, of many of the O’Neill’s currently tested, since they at least deserve that respect to be placed and helped. Looking at group of O’Neill’s that share a common haplotype I believe they are of the Haplogroup R1b1a2a1a1b4h SNP R-L226. In my research I have found a total of 7 O’Neill’s that maybe among those of the Dál gCais O’Neill’s. This sub clade is within R-L21, and is defined by the presence of the marker L226, also known as S168. Referred by many as the Irish Type III, it is concentrated in Central Western Ireland and associated with the Dál gCais kindred. I suspect that these are the O’Neill’s of Thomond!

1. The majority of O’Neill’s tested are of the SNP P312/S116 R1b1b2a1b an estimated 5,300 years old.

2. There is another group of O’Neill’s that belong to the SNP M222 R1b1a2a1a1b4b an estimated 3,000 years old.

 Sadly! To this day the O’Neill DNA Project is still in disarray with countless members ungrouped etc. Like I said before what we have is an agenda by those O’Neill’s that are chasing after the mythological figure Niall of the Nine Hostages M222 SNP in association with the O’Neill’s, and if you do not match the SNP M222, it seems that you’re on your own. Hopefully in 2012 the O’Neill DNA Project gets its self in order, and gives it members their respect to be placed in their respected groupings.

Those O’Neill’s of the Haplogroup R1b1a2a1a1b4h/ SNP R-L226 are eliminated from being O’Neill’s descendants of Niall of the Nine Hostages, and of the Ui Neill. They belong to the Dál gCais, who were a dynastic group of related septs located in the North of Munster, Ireland. The Dal gCais claim to be the descendants of Cas mac Conall Echlúath, who is believed to be the brother of the mythological Éogan Mór, son of Ailill Aulom, of the Eóganachta dynasties.

This group of O’Neill’s are now separated from the other O’Neill’s. They have more in common with those of the O’Brien surnamed than many of the other O’Neill’s.   

If you’re an O’Neill with origins in Central Western Ireland, match the y-dna haplotype below, and have no tested for the SNP. I would advise them to do so and it’s very likely they are of the Haplogroup R1b1a2a1a1b4h/ SNP R-L226.

 NOTE: Now what we need is for any of the descendants of these men to have the courage and come forward with a y-dna to find the differences among all these O’Neill’s starting with.

1. The O’Neill’s of The Fews: The male relatives of Don Carlos O'Neill & Don Arturo O’Neill.

2. The Clannabuidhe O'Neill’s: Don Hugo O'Neill of Portugal or any of his male relatives to come forwards with a y-dna sample.

3. The O’Neill’s of Ivowen: Alan O'Neill of Co. Waterford, or any of his male relatives to come forward with a y-dna test.
