Wasn't Autumn Lynn the name of a porn star? (ROFL, since I quit teaching high school, I'm not up on the porn star names anymore. Damn kids used to use porn star names on their papers, grrrr.)
Anyhoo, I think it is so you might want to avoid it!
I like Abigail Lynn. Or how about Avril Lynn? Ashley Lynn?
The one I REALLY like is Aislinn -- it's Celtic/Gaelic meaning "dream." Then you don't need to add a Lynn!
