Hi - I am also chasing a possible death at sea of my 4th Great Grandfather who may have been on this ship Etna. If anyone has access to the passenger list I would greatly appreciate if someone would mind to check if the following passengers may have been aboard this journey in Sep 1865 and any personal details which may have been listed. I would only assume they boarded in England.
DUKE, Isaac - Age would be approx. 43
DUKE, Ann - wife of above
