Hello

Am wondering if anyone can direct me to where I might find further information on John Glover who was a surgeon in the Royal Artillery (this is how John is named and listed on the death certificate for his son George - excerpt attached)). I believe John was born around 1780/1 in England, however, I'm yet to discover exactly where.
His wife was named Elizabeth (surname unknown).
The only information I can find (and this is if I have found the correct John Glover) is information relating to serving aboard the HMS Pyramus from 1811 to 1814, then the Sultan from 1814 to 1815 and then on the Ajax from 1815 to 1816. The Naval Officer and Rating Service Records, however, don't indicate what rank he was, or whether he was in fact a surgeon.
Unfortunately, this is all of the information I have on him. I'd appreciate any pointers :-)
Regards
Meg
