Hello Mary Becker, I am a McClinton. Our ancestors changed the spelling of our name in the late 1800 early 1900's here in Ontario, Canada. I have been doing genealogy for over 10 years, off and on, as time permits. I admit that I have run into roadblocks along the way. With the help of many distant cousins, we have traced back to Killyleagh, County Down, Northern Ireland in the late 1700's. How would a Y-DNA help me identify ancestors further back than that? Would there be links with others who have searched, done the Y-DNA and found names and places of ancestors that could be connected to our line? I am very interested in the concept of the Y-DNA and I was just wondering how fruitful it could possibly be. Could you recommend the better test to take. I have read the literature on the Y-DNA but I'm not sure if the higher number test would be more beneficial than the lower one in my circumstance. I know I am respomding to an older thread and I hope this is still relevant, as I am very interested. Thank you in advance and hope to hear from you. David McLinton.
