I adore it.
Penelope Antoinette is still in my Top 5 Girls Names, but alas, we are not having any more babies. We did not use it for our daughter because I honestly didn't care for the nickname
Penny and our (then 7 year old) didn't like the strong "pee" sound at the end of the name- he thought it had teasing potential. Still, overal, fabulous name and still a personal favorite.
