My late father, who was in the Navy in WW2, talked a lot about a his friend Harry Yarwood, who joined the Navy with dad in 1939. They did some of their training together, then dad was assigned to convoys to Africa, while Harry drew the short straw and got the Russian convoys, on which he died, I think on his third voyage.
I'd like to find out more about Harry. Some of my dad's information may not have been 100% accurate - he only really opened up about his wartime service when he was gone 80 and was mentally going downhill, but my mother remembered dad talking about Harry when they first met at the end of the war.
Sadly, I haven't been able to find anything out through Ancestry - where else could I look?
