Thanks Radcliff. It's certainly a possibility but I am not sure at all.
My John France should have been in his early 70's in 1861 so the one with the Blakeley family is a bit old but then they weren't very accurate with their ages.
My John France, as far as know, didn't have a daughter called Ann.
The children I have so far are:-
Henry b1812 Slaithwaite
Joseph b1814 Slaithwaite
Mary b1818 Slaithwaite
William b1819 Slaithwaite
Charles b1820 Manchester
Jonathan b1826 Manchester
Adam b1830 Manchester
All the older children moved to Manchester, married and died there with the exception of Mary b1818, I don't have a record of her after he baptism.
There are some gaps and I think there might be some children missing but there aren't any gaps around 1819 when the Ann Blakeley would have been born. I would have thought there should have been a child called Ann or Hannah as that was his wife's name.
Then there is Mirfield. Although not far from Slaithwaite, Mirfield hasn't appeared on any of the records for this family. Everything for John and also his brother, William, happened in Slaithwaite and then the two brothers moved their families to Manchester almost simultaneously.
So I am not sure
