From an English surname, itself derived from a place name meaning
"ash tree town" in Old English. This was a rare masculine name until the 1980s, when it gradually began becoming more common for both genders. Inspired by the female character Ashton Main from the 1985 miniseries
North and South, parents in America gave it more frequently to girls than boys from 1986 to 1997
[1]. Since then it has been overwhelmingly masculine once again, perhaps due in part to the fame of the actor Ashton Kutcher (1978-).
