You are wondering if there are any Mc Guinnness' from Killybegs, well you are reading a comment posted from one of them. My father is James Mc Guinness, B.1960 and his father was Edward (Eddie) Mc Guinness, Died 1959 from Granhy, a townland near the town itself. I am from a townland called Island, or sometimes it is referred to Old Fintra Road.
My grandmother is Annie Mc Shane, B.1927 from Beaga, Carrick and she married Eddie I think sometime in the 1930's. As for the Mc Shane side of it, some moved to America, some to Australia and some to Scotland.
