The short story
Vaughn is an American spelling of the Welsh surname Vaughan. The Welsh form comes from bychan, “small” or “little,” which mutates to Fychan in the grammar of a byname. It could distinguish a younger relative or someone of small stature, making nickname the closest catalog type. Vaughan, Vawn, and Vawhan are spelling neighbors shaped by Welsh pronunciation and English recordkeeping. Vaughan is also used as a form of an Irish surname related to McMahon, so not every family follows the Welsh route. The Welsh gloss is strong, but that regional alternative makes confidence likely.
