I read a couple baby name books for our two girls or boys during the search since we didn't ask the sex. I guessed girl both times and was right. Ultrasound seemed right brain dominate so I thought girl, and she is also left handed. Anyhow, classic-names-making-comeback? is a neat list for names popular before 1930 and now again.
One of the books said don't make a dumb mistake namining siblings Thomas and Gerald which would ultimately be Tom & Jerry.
