The O'Neill's Y-DNA

The O'Neill's Y-DNA




Only over 200 , or so O'Neill's have currently been tested their y-dna, and this is only a small amount compared to the vast O'Neill's through the world. Perfect example are the O'Neill's in the Caribbean, France, Portugal, Spain ,and South America. What we do know is that from the current O'Neill's tested (200 O'Neill's ) the majority belong to the SNP R1b1b2a1b , and the ones who have not tested for their SNP are R1b1b2 , and very likely they will be R1b12a1b once tested. It's speculated that they all seem to share a common ancestor possibly around 950 a.d. , who was this common ancestor? It's not known , but what is interesting is that they do match the surname Sterling and Williams, very well. A theory is that this group of O'Neill's were part of a tribe absorbed into the Cenel Eoghain, during the reign of the Domnhall of Armagh or better known as Domnhall Ard Macha Ua Neill ,or they were absorbed into the Cenel Eoghain in earlier times.

The O'Neill's y-DNA brake down to several different Haplogroups.

1. R1b1b2a1b5b O'Neill's the MRCA Niall of the Nine Hostages ,and founder of the Ui Neill dynasty, not of the O'Neill's surname.

2. I1b1a O'Neill's the MRCA is unknown , but this SNP is found in Spain and Sardinia.

3. R1b1b2a1b5 O'Neill's the MRCA is unknown. What is known is that this SNP is found in Finland, Norway ,and Sweden.

4. R1b1b2a1b O'Neill's the MRCA is unknown, yet this is the SNP found in the majority of O'Neill's currently tested out of 200 +.

5. R1b1b2a1a4 O'Neill's of Puerto Rico, the MRCA is Don Constantino O'Neill of Spain of the late 1600's . These O'Neill's haplotype is unique ,and has a strong connection to a group of similar haplotypes in Yorkshire, England, the Shetland islands , and Sweden, but no matches in any database the closest matches is estimated around 800 to 900 a.d.

There are 5 distinct SNP's and various septs, but only two of the SNP's , the progenitor or MRCA is known, and many of these O'Neill septs do not have a modal y-dna haplotype or a SNP. These various O'Neill's to my knowledge do not have a modal Haplotype,or have anyone that as aquired a y-dna tested. The O'Neill's of the Magh da Chonn, The O'Neill's of Thomond, The Clannabuidhe O'Neill's, The O'Neill's of Cor, The O'Neill's of Feevag, The O'Neill's of Ivowen, The Johnston Baronets of New York, and the O'Neill's of Fews (Spain). Of these septs none of their MRCA's y-dna is known.

The O'Neill's of the Fews MRCA or progenitor is Aodh of the Fews d.1475 , one of his descendants Sir Henry O'Neill of the Fews (Don Enrique O'Neill of the Fews) is the progenitor of the O'Neill's of the Fews in Asturias and Sevilla , Spain. No one of their respected sept as come forward to acquire a y-dna test ,and we do not know their SNP or Haplotype.

The Clannabuidhe O'Neill's progenitor is Aodh Buidhe SNP unknown .

The O'Neill's of Tyrone progenitor Niall Glundubh MacAedo d. 919 SNP unknown .

The O'Neill's of the Fews and Clannabuidhe both are of the House of Tyrone ,and it is assumed that they both share a common ancestor in Aodh 'The lazy Youth' O'Neill 1176 -1177. Also, the Maclochlainn and O'Neill's is assumed to share a common ancestor in Domnhall Ard Macha Ua Neill 956 - 980 the grandson of Naill Glundubh MacAedo.
