I am not sure whether we have communicated previously. My ancestor James Gimbert born around 1810 was transported as a convict for 7 years to N.S.W. in 1828. He married a Mary Jane Mahony in 1837 in Sydney. I have traced most of the ancestors of James and am particular interested in the Hackney line. I have searched for James's family in Cambridgeshire with no success.
Please reply as I would love to share any information.
