I recently had my Y-DNA tested at FamilyTreeDNA (Y37) and was surprised to find that I'm predicted to be I-M223, an ancient WHG haplogroup. I've got two matches (33 out of 37) with my surname (Callihan/Callahan).
Maciamo in his write-up on I2a2/P214 (the vast majority of which are I2a2a/M223) has a map that shows hot spots in 1) central Germany, 2) northern Sweden, and 3) SE Northern Ireland/SW Scotland:

The "The DNA of the Irish Gael" article at Irish Origenes (https://www.irishorigenes.com/content/dna-irish-gael) also has a map showing the same Ulster/Scotland area as strong for I-M223. There are significant numbers of Callahans in SE Ulster, although most are in south Ireland (around Cork). My earliest Callihan ancestor likely emigrated from Ireland to Pennsylvania in the 1750s.
Any thoughts/theories on how and when I-M223 carriers (presumably including future Callahans) made their way to SE Ulster?
