This name sounds a bit elitist and snobby, while Ashton doesn't. Must be the car. I would never use this name for females. The name sounds even more masculine than the definitely masculine Ashton. It would sound weird on any girls and women, even the tomboys and androgynous women. I hate it when people think this name is too close to 'ass'. It's not ''AAAS-ton'', it's ''AS-ton''!
Certainly not a feminine name! It's not overused so I like it. It sounds kind of modern too. So many male names are so old and dated. It's a nice departure from Ashton too, much thanks to Ashton Kutcher for ruining that name.
