Hi Susan

Part of the reason I had requested this information was to established if they had followed a naming pattern.
On a later post you mentioned the "Eleanor and Isabella" link, I don't think there is an Eleanor in Elizabeth Christian's family.
Both your and Elizabeth's Robert Henry don't always state their second name Henry.
My concern is your RHC stated his POB was Castletown, Malew , where Elizabeth's RHC did not seem to be born in Castletown.
I note on this posting that Margaret Agnes Joy did not know her mother's name , what of Robert Henry ?
Recently I tried (Amongst others) to establish the parents of a James Edward Callister for Anne Dunning , I think I found him , but because of missing christenings we were not able to totally confirm the link. Have a look at the postings in Dec 2016/Jan 2017

Knowing Robert's mother would help and if he did not know , that would also be interesting

Cheers
David
