Hello Casalguidi
I did indeed find information out about Elizabeth Hart from a person at the beginning of last year. It turned out that their ancestor William was my James' brother back in 1774 in Kent, and we still e mail each other to this day. In fact they are the only relative that I know from my dad's family.
I do apologise for not putting 'completed' on this thread, I have never noticed this baptism entry on the IGI so whether it has been added recently I don't know. However, when I did take a look I see that there are siblings of Elizabeth which I did not know about. So thank you for letting me know about this entry.
