I have a few old reference books on the convoys. What I have found is:
Merchant Ships sunk were Hybert (US), Massmar (US), Exterminator (Panamanian), Rodina (Russian), Heffron (US), John Randolph (US). The Exterminator was salvaged in 1943, and the forepart of the John Randolph was also salvaged after the war. From what I have, there were no dead from these ships (miracle!).
I'll poke around and see if I can dig up anything else.
