I know Franklin's been ruled out for 1, but I think MartinRyan is a bit out in saying the dates don't fit. Franklin embarked on his second polar expedition to the mouth of the McKenzie (vastly more successful than his first) in 1825 and returned to a hero's welcome in New York (only two seamen lost, both in accidents I believe) in 1827 or 28.

OK, so this is not a very constructive contribution. I just wanted to bring the thread back up the list in the hope that someone will come up with the answers.
