The only Edison I know is a girl, she usually goes by 'Eddie'. Apparently, her parents were expecting a boy (their first child had been a girl) and had intended to name him after the father, Edward. When she was born prematurely, they decided to just go with the name anyway. I think it's cute, but mostly because the fact that it's a boy name (she's a tomboy) is a bit of a running joke.

I've encountered this name on a baby girl. I wonder what statement the parents wish to make with a name like Edison. Perhaps they wish to celebrate the invention of the lightbulb? Do they hope the wee girl will become a great innovator?
I think all names ending in 'son' should be reserved for males since that ending denotes the meaning "son of__"... So it is strange to name your daughter "son of__".
As for Edison, I think it's a nice name for a boy. It's not too common.
