On a Birth/Christening search, all that the IGI says is:
"About 1787 Bonsall, Derby, England".
Yes, your point about the FLINT's living in Lea could well be valid. There were a number of FLINTs in the Dethick, Lea & Holloway area, as well as Crich, which is actually where I live.
Thank you for your help & suggestion of moving this thread to the Derbyshire Board.
Just as a matter of interest, on looking at this today, and having had to revise the Birth dates of both, I now realise that Henry FLINT would have been 37, and Sarah FROST would have been 19, when they were married.
Henry, it would appear, lived till he was 91, and Sarah died when she was 66, some seven years before Henry.
Thanks again,
Alan
