I'm relatively new to all this, but have been sent a load of information from my cousin which I'm sure she won't mind me sharing.
Richard Primmer (1781) was my gggg grandfather.He married Maria Jerram (1783) in 1804.I don't know who his parents were, but hers were James and Elizabeth Jerram (I believe they were relatively well-off farmers).Richard and Maria had 5 children that we know of (although I notice that Bob Swan has found 8!): Richard (1816), John (1818), Elizabeth (1820), James (1822) and Henry (1924).
I then follow down through Richard and Harriet, via Amelia Rosina and George Stares, whose youngest daughter Ethel Kate's first husband was John Clement Keefe.
Hope this is of interest to you, as your previous messages have helped me build up some of the "twigs" on my tree!
