Berkeley , family , of Gloucestershire

The Berkeley family's seat was at Berkeley Castle, Gloucestershire built in 1153 by Lord Maurice Berkeley. Lord Berkeley of Stratton (died 1678) ran the Duke of York's household and built himself a magnificent London house in Piccadilly. His descendants laid out Berkeley Square in the grounds. In 1679 George Berkeley made first Earl of Berkeley by King Charles II.

The fifth Earl of Berkeley, Frederick Augustus (1745-1810) took Mary Cole, a butcher's daughter as his mistress. In 1796 they married, Mary having borne the earl five children and later that year their legitimate son Thomas Moreton was born. Mary was anxious about the legitimacy of her adored eldest son William Fitzharding (1786-1857). In 1799 she and earl forged the Berkeley parish register with a false entry for a secret marriage 1785 to make all their children legitimate. On the death of the earl in 1810, the Berkeley Peerage Case was heard in the House of Lords and in 1811 the earldom passed to Thomas Moreton. In 1841 William Fitzharding was given the title Earl Fitzhardinge.

The family held estates throughout England, including the Manor of Cranford, the Manor of Harlington and the Manor of Harlington with Shepiston.
