Penelope!
Olivia is way over-used.
Penelope is pretty, has never been overly popular at any time period and so won't date her. It's historic and classic - the name of the Elizabethan Lady
Penelope Devereux, as well as up-to-the minute -
Penelope Cruz and baby
Penny in "Desperate Housewives".
There was a
Penelope at school and another at college and I've always thought how attractive a name it is.
