English: variant spelling of Wynn. Welsh: variant of Gwynn. Irish (Connacht): adopted as an English equivalent of Gaelic Ó Gaoithin 'descendant of GaoithÃn' (see Gahan), because Gaelic gaoth also means 'wind', and the English surname Wynne was taken as being related to the English vocabulary word wind.
Depending on who you talk with, the word “Wyoming” in Delaware Indian language means either "large plains" or “mountains and valleys alternating;” in Munsee language "at the big river flat;” or in Algonquin “a large prairie place.”
