Hello I am still searching for information about Birnie Brown(e) born @1759-1765. I have been able to confirm though written text that he was a son of James Birnie who became James Hamilton Birnie though his marriage to Margaret Hamilton in Edinburgh City on September 9, 1753. Birnie later marries Catherine Grace Creswell which tells us that he was not abandoned by James.
Assumption is he is a natural son of James and a female Browne. Any ideas on where to search further would be helpful.
Regards,
Gary
