| Background: The surname is originally French, being first borne by Fulbert, Great Chamberlain of Robert, Duke of Normandy, who granted him the castle and lands of Croy or Gray in Picardy which he thereafter assumed as the family surname. His daughter, Arlotta, is said to have been the mother of William the Conqueror. In England several families from this source were raised to high rank, and spelt their name ‘Grey’. From the Dukes of Suffolk came the amiable and accomplished Lady Jane Grey, who was an innocent victim of the ambitions of her father. She was proclaimed Queen of England and reigned for nine days in 1553, but she perished on the block in February 1554.
Variations: Gray, Grey, Groy, Grays, Graye.
