Dear Rog,
Thank you very much for your reply.
We have found the Army record which mentions the details that you mentioned. Unfortunately, we seem to be stuck there.
He had three children in Hobart Town 1839 to 1845 and then continued his family in Onehunga (Auckland) New Zealand until he died in 1860.
The items that we cannot find despite searching are:
1. Who was the brother that he went to join in the 51st Reg't (when Edward transferred out of the 10th Reg't)
2. A birth or baptism certificate
3. Whom his parents were and whether they might have been in the military
We were hoping to back-trace from the brother's records.
The marriage certificate is also proving to be very elusive. This may be because Catholic ceremony marriages were unlawful until 1837, so I don't know if it might be that they got married in an Anglican church near Chatham, Brompton Barracks. Derrom is a Huguenot name, so who knows, although her father and some brothers also ended up in Onehunga, New Zealand, where they mostly had Catholic ceremonies.
Edward and Ann seemed to avoid laying too much information within the Regimental records, probably for their own self-protection.
Do you think that it might be possible to widen the search to include Anglican church records nearby?
Again, thanks everyone for your help. I know how involved this can become.
Best wishes,
Marc Kelly
