Many thanks Harry. I've been trying to fit dates together today. Your William, born 1730 seems to fit the bill. However I'd still love to know who Margret's mother was. Two Margts. born in Patrick around that time. Both with William Kelly as their fathers. One in 1750, and one 1758.
William Kelly and Alice KEON had a daughter named Margt.

In Malew 1756 a Margt. born to WK and Margt Quayle...they had other children, Margt. in the middle.

Also 1759 in Marown, a WK and Ann Callister had a Margt.
I'll let you know how events progress.
I really do appreciate your input.
Best Wishes, Adrienne
