In summary

From Middle Dutch Friese, but also Vriese, Vrese, from Old Dutch *Frieso, probably via Old Saxon *Frēso. Borrowed and re-borrowed, at varying times in history, from Old Frisian Frēsa, Frīsa (modern West Frisian Fries). Probably ultimately from Proto-Germanic *frisaz (“curly, frizzy”), named for their curly hair. Also compare Latin Frisii.
Initial v- is expected from natural development from Old Dutch, in which voicing of initial f- to v- occurs naturally. The modern form with f- is probably influenced by the Frisian endonym. However, the original voiced consonant is retained in the common surname de Vries.
