hi christine,
I seem to have my self in a mess again,
so ill back track,
info i have confirmed as follows
patrick key born 1795 patrick
father thomas key
wed catherine corriss 1789 patrick

info not confirmed as yet,
thomas,s date of birth approx 1767ish,
and suspect/maybe his father is also called thomas,= the one that you refer to.

as i do have a mention in my notes some where of a gilbert key..need to look back at my notes..plus will check out brians site,
when i have confirmed above info.
thanks for all your help..
regards yvonne.
