Lol, same here :). I tried Mrs Howell after "milionaire" gave me the husband's name, but that wasn't enough. Been too long since I watched any of those episodes, and I'm not sure all the names were the same in my language anyway.
That's funny, because the show's creator Sherwood Schwartz admitted that the seven were done as ammo55 indicated, except the Skipper did double duty, taking on Gluttony and Wrath. Gilligan (the one the island is named for, dressed in red, ruining all attempts to escape, and generally causing mayhem) represented the devil. :)
That's the only way a lot of us were able to get 100%. Never seen an episode of the show, but know the theme song pretty well. Couldn't tell you why, though.
Professor = Pride
Ginger = Lust
Mary Ann= Envy
Mr. Howell= Greed
Mrs Howell= Sloth
Skipper= Anger
Gilligan= Gluttony
