Many thanks for all the info posted - I have recently contacted Gordon Byatt and will be back in touch with him after the xmas break.
The Byatt family is my son in law's lines and I supposed because they lived in the same area's (Sandon) for so long the same name's keep cropping up in connection with later marriages. I have a John Skipp born 1789 who married Catherine Barnes born abt 1812. Their daughter Ann Skipp born 1845 married Henry Edward Barnes, I dont know if there is any connection between Catherine barnes and Henry barnes who became her son in law, other names that crop up loads are Hills, Kingsley, Hatchet. John Skipp born 1789 was a brother of William Skipp who was the grandfather of the Elizabeth who married Alfred Byatt.
If anyone is able to look for Edward Byatt and Mary Hollingsworth marriage info for 14 nov 1812 in sandon and see if their Edwards father or witness names are recorded I would be very grateful.
