Western town or from the west
Westynn is a modern American elaboration of the English surname and place name Weston. It combines the cardinal direction 'west' with the Old English suffix 'tun', meaning an enclosure, settlement, or town. The double 'n' and 'y' spelling is a contemporary stylistic choice intended to give the name a unique, creative flair.
