I'd never heard of
Indigo being used as a name until I came to this site. And even worse it seems to be used as a boy's name. I don't know, but it certainly seems like it would be a girl's name to me. However, it also reminds me of
Inigo, which is a boy's name. I'm so confused. Anyway, I don't like it.
Indy is an okay nn. For
Indiana. Like
Indiana Jones. :)
