One of my cousins' best friends' name is Izabelle. I love this spelling! She shortens her name to Izzie with Ie at the end. She's named after the bassist Izzy Stradlin, from Guns and Roses, but I think she's happy about that.
OttilieMaisie I think I know who you're on about (your cousin is Prudice C.- I know her) Izabelle is an ace spelling of the name! I love how rare it is!
