Su:
I agree completely that these are very good probables for being Joseph's parents ... I was so sure I'd find him in their family when I went through the PR.
I don't know what to think. This would go to show that there was a church in Thorpe Market in the time before the new one being built in 1796, so, if this is his family, why no Joseph.
Now that I think his birth might have been 1788-9, not 1790, the fact that the register is extremely damaged for the few years (if I recall correctly) prior to Elizabeth's birth....
I'll check for deaths of children that might explain the gap of six years.
Thanks for your great work on this puzzle!
