thanks Carole for the replies.
I don"t have a copy of the marriage cert unfortunately,or Eliza"s maiden name.
Im very much at the beginners stage to be honest,but the info you"ve found will no doubt help.Thanks for that.I will have a go at tracing back..i"m quite looking forward to it,but it"ll no doubt be a minefield lol.
Much obliged and many thanks
Chris
