Thank you, Tony and Brian for your replies. You've both made the right assumption; I'm not very experienced with RN records as this research on Benjamin is the first time I've needed to come into contact with them. You've both explained a lot that I didn't know, which is very helpful.
I will contact the NA and see what the procedure is for trying to obtain a copy of the information from 1911 and hopefully I will get lucky.
To clarify, Mark, Benjamin is listed as "Lieutenant RN, deceased" on his daughter's marriage certificate from 1839. After our exchange of yesterday, and looking at dates, I suspect the fellow in the photo would be 4g-grandmother Jemima's 2nd husband. This man seems to have been important to my 3g-grandmother Clarissa who is the one who has kept the photos. He witnessed Clarissa's marriage certificate. (Note different number of g's!). I'd say a later generation has annotated the photo, based on family stories. I have attached the photo. The man is not young, but certainly not elderly - stocky and middle-aged, so his age fits well with photography and what I know of him so far.
My ASSUMPTION that Benjamin died in 1825 is based on a few things, but certainly not accepted 100%:
- My 4g grandmother, Jemima, remarried in Oct 1827, so Benjamin had certainly met his demise by then,
- Benjamin's last child was born in 1820,
- He is supposed to have been in Bristol and there is a death in the parish registers of the correct church (St John the Baptist, Bristol) for a Benjmain Thomas in 1825,
- As it is clear that the photo I have is not of Benjamin, the stated age at death of 32 could be possible, although as has been noted, that would make him very young to be doing his lieutenant's exams in 1811.
There is one problem with the 1825 death - his first daughter (3g grandmother, Clarissa) seems to have been baptised in
1826 at the age of 8yrs, with her father, Benjamin, being listed on the baptism as an engraver. Perhaps her mother, Jemima, didn't say he had already died and it was actually the fellow who would become her 2nd husband in attendance? I'm not sure about this, but certainly Benjamin was deceased by the middle of the following year, 1827.
More puzzles to solve!
