I have a marriage between Mary Davy & John Harrowing in Costessey, Norfolk (1765). I wonder if there is a relationship with William Davy?
It's a bit of a long shot, but later on chronologically in the Whitby branch of the Harrowing family, there appears to be property in Suffolk (Occold and Rishangles).
I am trying to find evidence to prove that my branch of the Harrowing family travels backwards from Whitby through London and Kent (Maidstone) before finding its origin in Norfolk (Norwich hinterland). I suspect that Suffolk may have been on their path and would not be at all surprised to find that my Mary Davy hails from Suffolk.
Has your research found any siblings for William Davy or evidence to prove where he was born?
