Robert FitzRoy
Robert FitzRoy was born at Ampton Hall, Ampton, Suffolk, England, into the upper echelons of the British aristocracy and a tradition of public service. Through his father, General Lord Charles FitzRoy, Robert was a fourth great-grandson of Charles II of England; his paternal grandfather was Augustus Henry FitzRoy, 3rd Duke of Grafton. His mother, Lady Frances Stewart, was the daughter of the first Marquess of Londonderry and the half-sister of Viscount Castlereagh, who became Foreign Secretary. From the age of four, Robert FitzRoy lived with his family at Wakefield Lodge, their Palladian mansion in Northamptonshire.
Robert Fitzhamon
Robert FitzHamon, probably born in the 1040s ior 1050s, was the son of Hamo Dapifer the Sheriff of Kent and grandson of Hamon Dentatus ('The Betoothed or Toothy', i.e., probably buck-toothed). His grandfather held the lordships of Torigny, Creully, Mézy, and Evrecy in Normandy, but following his death at the Battle of Val-ès-Dunes in 1047, the family might have lost these lordships. He is said to have been relative of William the Conqueror, but the nature of the relationship is unknown.
