I think, though am not sure, that Captain Gaillard's book had some sort of list. Probably the best list would be held somewhere like the Imperial War Museum? Voyage magazine just had two lengthy articles about the 65th anniversary of the sinking.
I am lucky to have an Athenia lifejacket singed by about 100 survivors. It still has water stains on it. You should be able to order a copy of the Athenia articles from Voyage magazine from www.titanicinternationalsociety.org
