Hi,
Too bad you haven't got any reply yet, but maybe you want to review your original message. I, for one, couldn't follow it.
You start the message talking about a Patrick and Catherine, then suddenly we learn that George died in 1857. Who is he, and what is his link to P and C? You then say that he was in Darlington in the 1871-91 censuses, but how can this be if he died in 1857?
