My great grandparents James and Ellen (McCann/McCaslin) Kerrigan were very close to, and possibly related to Charles Glackin. I believe that he at least lived in Enniskillen; I don't know yet where he was born. However, in looking at the 1864 birth index for Ireland, I came across a James Glacken, whose birth is recorded in the Reg. district of Inishowen, Co. Donegal, vol. 7, pg. 152. Happy hunting.Margaret J.
