The farm Frøystein by the Ulvik fjord is commonly called Fryste. In 1614 the name was written Frøstemb – an obvious Danish influence – and the form Frøsten was used up until the land register in 1886 and 1907. It is probable that the name of the farm originally was Frystvin; a vin-name. Thus it has no connection with neither Frøy (Norse fertility god) nor stein (stone).
