 In one scene the three women are talking to each other about who  they would like to marry. Marilyn Monroe (qv)s character says she  wouldnt mind marring Mr. Cadillac. Lauren Bacall (qv)s character  replies "No such person, I checked". There was a Mr. Cadillac. He  was the French governor of Canada (founded the city of Detroit and  in 1710 was named the governor of Louisiana). The Cadillac was named  for him and his surname lives on in the form of his descendants.
