Following confirmation of the A738/BY198 haplogroup for some of the M222 Irish Curleys, several of the other M222 Irish Curleys tested for this same SNP. The tests reveal that they are unrelated to the A738/BY198 lineage of East Galway. So it looks like we now have yet another distinct genetic lineage (at least one) in some Curleys of the Connacht area, including one from the Aran Islands and one from Sligo. Likely, this is due to NPEs that have fragmented what was originally a single Curley lineage of this area. I've reorganized the project groupings according to these latest test results.
Members of Group 5 are encouraged to purchase the M222 SNP Pack to determine their haplogroup within M222. Identification of the terminal SNP is the only way to confirm lineage groupings among these individuals whose STR signature is ambiguous.
