GRAHAM Family, Great Amwell

[DebbieG]

I am looking for any information on the Graham family from Great Amwell.

I have a Robert Graham who according to the 1841 census in Highgate was born about 1778 (he was working as a gardener then and living at the Red Lion).  One of his sons Thomas Graham who was born in Ampthill Bedfordshire lived and worked in Hertford and there is a baptism in the IGI for Robert Graham s/o John & Elizabeth at Great Amwell in 1779 which would fit in nicely for the Robert I am looking for,  however the only other IGI entry for Grahams at Great Amwell is a baptism in 1739 of a John Graham s/o Hector and Jane.  I can't see any marriages or any other entries that seem to fit this family - has anyone got any ideas?

TIA
