I'm looking for a John (born 1783) and Elizabeth Gammage (born 1787) (nee Clark) - I have a marriage certificate for them for Hanslope, Bucks 1809 and a son Henry 1813. I also have a death in Bicester of a John Gammage 1866 and a death in Headington of an Elizabeth Gammage in 1866 but I can't tie them to the Hanslope Gammages.
