Thank you all for your replies.
The Michael Spain I’m looking for is definitely the one baptised at Spetisbury.
His father, Cornelius, was born in Dublin in c1818 & married his mother, Elizabeth, in Wirksworth, Derbyshire, in 1838. Cornelius was a hawker & the family were living in Devon at the time of the 1851 census.
Michael’s younger brother, Thomas, also served in the Navy & then settled down in Hampshire. Thomas’ naval record gives a list of all the ships he served on & the date he left the navy, so I was hoping there might be something similar for Michael, but finding out what happened to him is proving to be as difficult as tracking down his father’s death…
Thanks again,
Ju
