Testing the Y-DNA paternal line, he matches, in a genealogical time frame, 3 Foley, 4 King, and 1 Burke. I understand the first 3 names are common in Galway.
Two Foley only tested at 12 markers, and are full matches, but the third matches my Folan at 62 of 67 markers, along with a Burke. The distance to a common ancestor could be as much as 300 to 500 years! This Foley is known to have been a Folan, the name changed in early 1800's Ireland.
Of the four Kings, the matches are full 12 of 12 for two of them, and 63 of 67 and 60 of 67 for the other two.
My father-in-law's Folans are from Cor Na Ron or Cornarone, west a bit from Spiddal, Co.Galway, in the early to mid-1800's.
