Hi I am trying to find out some information on my great uncle, Thomas J Mattey. I have been told he served in the Merchant Navy, and died at Sea in WW2. His brother said he served on the SS Taberg, which was sunk by an Italian submarine off Gibraltar on 6/6/1941. There were 15 casualties. Unfortunately, this is all I know. Does anybody know how I can find out if he was one of those casualties, or whether he died on another ship?
