This name certainly lingered on in England into Tudor times. An earlier post of mine tells that I stumbled across it in county of Devon records of that era. Today I have stumbled on it again, in Tudor Dover Kent, records - Fridwith (Frideswide), daughter of Sir Thomas Frowyke (Chief Justice of the Common Pleas) and wife of Sir Thomas Cheney. It looks so odd alongside the usual crop of Annes, Margarets, and the like.
