Hallo, Tom Gunning, from Houston Texas.
My paternal great grandmother was born Margaret Gunning. She married to John Devaney and lived on a farm John owned jointly with his brother, James Devaney in Kilmacowen. Margaret Gunning's mother's name may have been Ellen, but I have no other information
My grandmother was born in 1891, so Margaret would have to have been born between 1860 and 1870.
I'd love to hear from you if you notice any connection. I have very little information about the Gunnings other than this, although I have a very old silver thimble enscribed "E. G."
