Any other ideas? Even something stretching it...
Lucinda (personally not my taste but it could work)
That's all I can think of right now. Even Indy/Indie by itself could work if you truly love it. I know a girl who is named Emmie and she loves her name even though its "nicknamey". Some nicknames can also work as first names, and I think that Indie could possibly be one of them. I wish you well :)
