I don't hear
Ivy League but I'm not American.
If it bothers you could you use two names?
Ivy Simone LeeIvy Louise LeeIvy Jane LeeIvy June LeeIvy Jacqueline LeeIvy Jessica LeeIvy Josephine Lee
Ivy Leanne is pretty.
Ivy Leandra
Or maybe there's another family name you're a fan of?
I would just go with
Ivy Lee. It's a good name.
