That in Ye Olden Days,
Caroline wasn't considered a prim or prudish name in certain circles.
Ever read "The Crimson Petal and the White?" It's about a prostitue in
London in the 1880's named Sugar who hooks a rich benefactor. She has a friend who is described this way: "Like many common women, especially prostitutes, her name is
Caroline."
And I just recently read "Bowery Girls" about two street girls in NYC in the same time frame.
Molly is a skilled pickpocket and
Annabelle is a prostitute. They start working in a settlement and the lady who runs it uses the name, I forget,
Elizabeth? Anyway, she reveals to them that she was once a street child and her name was
Caroline, a name she changed when she set out to become respectable.
