Hi Alan,
Thank you for passing that along.
I did actually find a link to that familysearch site not long after I made my original post. I found a marriage document, not the exact one that you posted, but something similar.
I tried to find a baptism for Thomas in Stoke Ferry, and couldn't find one, so maybe if he was baptised in Norwich, that could explain why I couldn't find anything.
The info I have says he was born in Stoke Ferry, but could it be possible that the parents may have taken him to Norwich, which seemed to be a bigger city, to be baptised?
I know that Thomas and Elizabeth had their children baptised at All Saints church in Stoke Ferry, but if Thomas was taken to Norwich, or was actually born in Norwich, that might explain why I couldn't find a record of his baptism in Stoke Ferry.
As far as Richard and Ann Salmon being possible parents, that makes sense, as both those names show up regularly throughout the generations. Thomas had a son named Richard, and the name Ann shows up several times as well.
I have something else I was wondering about. There was also a George Salmon in Stoke Ferry around this time. He was married to a Susan, or Susannah, and their children were baptised in Stoke Ferry a few years after Thomas and Elizabeth's children were. So I'm thinking he and my Thomas Salmon would have been close to the same age.
I'm not sure how many people lived in Stoke Ferry in the late 1700s / early 1800s, but with it being fairly small, I'm wondering what the chances would be that my Thomas and this George Salmon may have been related? I've always been of the impression that usually when the same surname shows up in a small town / village, that usually they're related.
