Hi
I saw your enquiry last night and it has had me thinking.
Thomas who married Sarah Brown was born in 1764. His father was George born 1726 who married Sarah Walker in 1747. Thomas and Sarah had nine children, one of whom was Margaret born 12th August 1796. She married William Potts 9th May 1814 and had ten children eight daughter and two sons.
I am descended from George and Sarah's son John who was born in 1766.
I can tell you more, but it would be easier if I know whereabouts you live and what your email address is.
All the best
Mike Havelock
