Hello drgug,
Derrykillagh was another old spelling of Derryhillagh.
The results of DNA testing for the Wilson group done is on Familytree DNA, All have done the Y700 test as it had the best results which now show which family we each belong to in Fermanagh, we know some with the same DNA moved to Tyrone.
I have been looking for a Wilson descended from Thomas for some time, the original Wilson settlers who lived in Topped mountain (Mullyknock) in the early 1600's may have been the ancestors, George Wilson was the other Wilson from the early 1600's retired to Lisbellaw and had son and a grandson George, would like to find a descendant, He was from England.
Ancestry dna test is only a Autosomal DNA test, very general, Ydna test is the only way to get a pure male line result and a Mt Full test is teh only pure female line results.
regards
Colin Wilson
