Hi Ravelin,
Good to know you also found the marriage record.
I'm also descended from Edward born 1750, but then through his son Jeffery. I've not been able to find his marriage to Elizabeth, who was born in Oundle, Northamptonshire (according to the 1851 census).
Have you managed to trace any of the other lines further back, i.e. Elizabeth Webb, Mary Ellis, Sarah Puttock? It would also be interesting to know if you've found any other information on the families, other than what's in the parish records.
