Hi to the Vicar's wife,
I wonder if you would be kind enough to see if there are any members of the Pigg or Pigford family in your database and the Towdoff/Toaduff/Todiff family. They moved around the Durham area but I know they were around from about 1784 in Durham, before that they were in Gateshead.
As they are unusual names with so many variations on the spelling I have been having problems tracking them.
Thanks for your time, Kind regards,
Kathryn
