Ashtone / Ashton

Ashtone is a modern English name, likely a variant spelling of Ashton. The name Ashton itself is derived from an Old English place name, meaning 'ash tree town' or 'settlement near ash trees'. Place names becoming surnames, and then first names, is a common linguistic evolution in English-speaking cultures. The addition of the 'e' at the end is a common contemporary trend to feminize or modernize names, though in this case, it's still predominantly used for males.
