The ancient family of de Berkeley deduces its descent from Hardinge, a younger son of one of the kings of Denmark, who came over to England with William the Conqueror, and fought at the battle of Hastings. His son, Robert FitzHardinge, obtained the Castle of Berkeley for his fidelity to King Henry II. [John Burke, History of the Commoners of Great Britain and Ireland, Vol. I., R. Bentley, London, 1834-1838, p. 469, Berkeley, of Spetchley]
