FYI - I have obtained a copy of Edward Hammer death certificate - states that he was from England and had been in the Commonwealth for 70 years at time of death. Spoke with a relative today and he believes he was on a ship at the age of 15 (possibly a cabin boy) and jumped ship. It is rumoured that he was originally from Holand and his mother placed him on a ship bound for England at the age of 10-12 years due to a plague outbreak in Holand (research shows there was a smallpox plague 1870-1872)
I haven't been able to identify any ships with his name on it

Cheers
