Thanks for your reply! I had a genealogist do some research on my family. Although he couldn't definitely find my great grandmother, Mary Ellen Gilleece, he thought she came from a family in Aghyoule where the mother's name was Anne, father's name was James.
My great grandparents, Ellen and John Reilly, were married in Knockninny, Derrylin, Lisnaskea in 1882. The witnesses were John Brady and Kate Gilleece.
I'm planning to go over to Derrylin in early August to at least see the area where they lived.
