I this thread on /tg/ earlier so far this is what I got.
-An elven trio one short of a former barbershop quartet (the former fourth member left because of creative differences
Van Oaken - The gentlemanly one, and a skilled banjo player, also a crack shot with a pistol.
Haggis McMaple - a rather un-elvenlike person, large and strong. He speaks with a Scottish accent and has a love of the caber toss.
Sawtree Bill - Short and stout, one might mistake him for a dwarf. He has a love of gold and riches.
As a possible event to transpire mid-route, the trio return to their old singing ways, crooning on about old sailors tales and the sea, and refuse to work. Their song must be broken to continue the voyage, but beware, for they are skilled at both singing and rhyming, so the PC's will have some trouble coming up with lyrics or words to break the song.
-Four of them go by the name Hamish, but only one of them is telling the truth. No-one on the ship actually knows which one is really called Hamish. They don't even look alike, and one's a woman!
