Hi Carolyn
Unfortunately, I can't help you with your specific question, but I was wondering if you could help me.
I'm descended from Thomas SARJEANT who was transported to Australia in 1827. It was indicated on his 1878 Death Certificate that he was from London, and his parents were William SARJEANT, a postman, and Elizabeth CHAMBERS (I appreciate information on Death Certificates depend on the informant, which in this case was his widow).
Anyway, I've esitmated William's birth as 1775, so a death of 1845 is quite prossible. I know its only a long shot, but wondering if your William could be my William (same spelling of surname), or even a relation? I've come to a brick wall on my SARJEANT's in England, apart from what is on the Australian Death Certificate of my Thomas SARJEANT.
