I Have a Second Great Grandfather George Blackford B Abt 1787 IN Kemble Wiltshire England There is a Christening Record at Burwash Sussex on Aug 17...
George married Charlotte Cuss on Dec. 17, 1809 at Oaksey, Wiltshire, England. They are both in the 1851 Census at Ashton Keynes, Cricklaid district.
They are 2 separate people,The George baptised in Sussex has a wife Ann. Your George as you know has a wife Charlotte. The records are in the 1851 census but Family Search also has this record.
cheers.
Ann.
