I've found a baptism for Henry in 1837!
Henry Pearce son of Joseph & Grace Pearce 7 May 1837 in Broadhempston. Joseph was a baker at that time. I've also found the baptisms of Henry's siblings - Joseph listed as a mariner for both.
Henry Pearce, railway labourer of full age, son of Joseph Pearce, a fish dealer, married Sarah Jane Hearne aged 20, domestic servant, daughter of William Hearne, cabinet maker at Ipplepen 9th July 1865, both otp.
