Hi Marion, thanks for taking the trouble to search Ancestry and FMP.
No, I do not hold a current subscription to Ancestry but I am in touch Theresa (my cousin once removed) who has posted most of the photos and documents for William Walter Frederick Joy on there. In fact, I have supplied her with quite a few items as I hold the medals and torpedo badge and associated letters.
I did find the Wrecksite info on line but I haven't ordered the full document as it appears to indicate just 6 people names; those of the six that died. I clearly need the full crew list to prove William WF Joy was on the SS Copenhagen when it was sunk & hence received the torpedo badge. I have researched the Board of Trade papers at The National Archives but there is nothing giving the names of crew receiving the torpedo badge.
