I first heard this name when I was little, in a book called "Lisa and Lottie". In the book, two girls by those names attended summer camp. They looked exactly alike and concluded that they were identical twins, seperated due to a divorce. Each assumes the other's identity and go to the other's home when summer camp ends. Sound familiar? Yep, this is The Parent Trap. The book was written in 1949 by a German author, Erich Kästner. The film was first adapted in 1961. The book is definitely better.
I first heard this name in a story we read at school a few years back. Lottie was a girl who didn't seem to live anywhere, stole food and other various necessities, and had a big thing for Mr. Goodbars. She befriended a girl, who's name I can't remember, and they went to some store and stole a bunch of junk by hiding it in Lottie's giant hat. They got caught and Lottie wasn't seen again. It was a good story, but I cannot for the life of me remember what it was called.
