I just hate this name. I really hate it. I just hate it. Did I mention that I hate it? I hate it. It's just yuk. I have no other reason than that. I just don't like it.
Gone With the Wind was published in 1936, so if Bonnie began getting common around 1928, it can't be due to the book. Also, Bonnie Parker of Bonnie and Clyde fame was born in 1910, so the name was in use at least that early.
God, with a name like Eugenie Victoria, it's a crime to use Bonnie. Oh, well, it's just a work of fiction, after all.
