Geoffrey de Mandeville
(died c. 1100) may have been Constable of the Tower
of London. His surname comes from the town of Manneville
) Little is known of him before the Norman Conquest of England.
An important Domesday
tenant-in-chief, de Mandeville was one of the ten richest magnates of the reign of William the Conqueror
. William granted him large estates, primarily in Essex
, but in ten other shires as well. He served as the first sheriff of London
, and perhaps also in Essex, and in Hertfordshire
He married firstly Athelaise (Adeliza), by whom he had a son William, and a daughter Beatrix (Beatrice), and possibly others. He married secondly Lescelina, by whom he had no children. About 1085 he and Lescelina founded Hurley Priory as a cell of Westminster Abbey.
His lands were inherited by his son William de Mandeville
. His daughter Beatrix (Beatrice) was the wife of Geoffrey, whom some have speculated was a natural son of Eustace II, Count of Boulogne
