A last name style choice with the sounds of Grayson, Graham, Weston, and Clayton, but ranking well outside the US Top 1000, unlike its counterparts. Given to less than 10 babies in a recent year, Grayton is a familiar sounding but little used option.
 
Grayton likely derives from the Old English words græg meaning "gray" and tun meaning "settlement" or "town", coming together to simply mean "gray town". However, other sources suggest it could also be a variation of the aforementioned Grayson (meaning "son of the bailiff or the steward"); it could be an alternative to Graydon (meaning "gray hill"); or, it could mix some of these meanings together, to mean "the steward's settlement".
