Has Grayson gone to the girls?

I have consitterd [name]Grayson[/name] for our baby if it is a girl (spelled gracyn), but I also like it for a boy. I am concerned that it has the potential to become a girls name, like [name]Jordan[/name], [name]Shannon[/name] and [name]Taylor[/name] have all gone to the girls. What do you think?
