I have a Bridget(Delia) Farrell in my tree, born 1860's
(don't have exact date) in the parish of Killererin, near Tuam
Co. Galway. Siblings: John, Michael, Ellen, Mary, Margaret and Anne.
Parents: Michael Farrell and Mary Coughlin of same area.
I have the details of all this family as they married locally,
except for Bridget, perhaps she emmigrated and is the one you
are looking for. Have you found any more about her since your post?
