Hi Ruskie,
Food for thought, some valid points - I did wonder about the age, whether the crewman could even be the age I would expect William to be in WW2, but with the photo not being close up enough, I wasn't sure.
They couldn't be related, so if it was not William he would be someone else entirely.
There were 34 men in the crew with an age variation of 17-71.
In the case of William, it is possible that he could have served during WW2 at sea, as he went to sea in 1927. That's partly the reason I was looking at this photo after I found a William Wilson in the crewlist. Such a common name though, that there's no way really of knowing whether he is any of the many William Wilsons I have found in different crewlists.
However, he may have to go 'back in the drawer' for a while.
Thanks for balancing my thinking.
Regards Eliza.
