Hi All
I quick update on the information I found - we got back as far as William & Sarah Grantham who were both born in Tysoe in the 1790s - and I didn't have access to the records, well I sent for some and they have arrived, so from the Registers of Tysoe in Warwickshire -
1815 Dec 26th William Grantham married Sarah Winter
1793 Feb 3rd William s/o Robert & Mary Grantham baptised
they also had Thomas 1791 (died 1816), Ann 1798 and Elizabeth 1803
finally a marriage 1790 Oct 10th Robert Grantham to MAry Hemmings
So there you go back another generation
