Thanks for those links Lizzie and Brian. I will peruse later when I get home.
Thanks Jeanne - I think I am barking up the wrong tree . . .
But will go there later if necessary - thanks for the reminder.
Further research and contact from the distant rellie in England reminds me that the Joseph I am after was born in 1703 as from his gravestone - so, unless that one I was so hopeful about is way out with his age, I am onto the wrong marriage.
(But looking at the gravestone again, - - I just don't know!) Read further . . something very odd here.
Just when I thought I was tying up some loose ends!
We have a marriage in 1729 for a Joseph Gaunt to Sarah Hinscliff but it takes place in Calverley and is by banns - which, Borthwick Archives tell me, means there isn't much more to be learnt from other documentation. That marriage says 'both of this parish . . . so what was farmer's son Joseph doing in Calverley - - taking time out from the farm??
And I still can't find a birth for Sarah to fit this marriage.
The gravestone says Joseph Gaunt of Upper Denby, was 60 at death in 1789 - so I don't know what's going on there. Sarah died in 1791 but age at death isn't clear. Also in the same grave are Joseph Gaunt of Stubbing and Hannah whom we presume to be his son and daughter in law - (and his infant daughter Elizabeth.)
I'm lost.
Will have to sit down and have a good think!
