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.
Charles FitzRoy, 2nd Duke of Cleveland
Charles Palmer, later Charles FitzRoy, 2nd Duke of Cleveland, 1st Duke of Southampton, KG, Chief Butler of England (18 June 1662 – 9 September 1730), styled Baron Limerick before 1670 and Earl of Southampton between 1670 and 1675, was the eldest son of Barbara Villiers, later 1st Duchess of Cleveland, and one of the illegitimate sons of King Charles II of England, Scotland and Ireland. As the putative son of Roger Palmer, 1st Earl of Castlemaine, his nominal father, he was styled Lord Limerick from birth. His birth marked the separation of his parents; Lord Castlemaine, a Roman Catholic, had him baptised into the Roman Catholic faith, but six days later the King had him re-christened into the Church of England.
