Yes, Trish, I had seen that list and he could well have died at sea. The main problem I have is I am having difficulty in finding his wife Elizabeth Trott born 1844 Bristol in 1881.Found one entry that could be her but she is classed as married, also their is a death entry on FreeBMD for a William Trott in 1877.
At this moment I cannot afford to buy a death certificate, so was hoping someone could look up the records at the BRO.
