Robert de Beaumont; allegedly 1st Earl of Leicester of the c1102 creation. [Burke's Peerage]

------------------------------------

On Leicester, Earldom of [Burke's Peerage, p. 1671]:

Robert de Beaumont, a companion in arms of William I (The Conqueror) at Hastings was granted after the Conquest much land in the Midlands of England, but most of it was in Warwickshire rather than Leicestershire. Indeed his younger brother became Earl of Warwick. Robert also held territory in Normandy and is usually referred to as Count of Meulan. He was a leading political figure in the reigns of William II and Henry I and on the death of one Ives de Grandmesnil in the First Crusade, the funds for campaigning in which Ives had raised from Robert on the security of his estates, [Robert] came into full possession of them, including a sizeable part of Leicester. The rest of the town was granted him by Henry I and it is possible that he became Earl of Leicester.

woman Isabel Elizabeth de Vermandois‏‎, daughter of Hugh de Crepi Magnus , Duke of Burgundy and Adelaide de Vermandois‏.

Isabel (or Elizabeth), widow of Robert (DE BEAUMONT), COUNT OF MEULAN and 1st EARL OF LEICESTER (died 5 June 1118), daughter of Hugh DE CR.PI (styled "the Great"), COUNT OF VERMANDOIS (younger son of HENRY I, KING OF FRANCE), by Adelaide, daughter and heir of Herbert, COUNT OF VERMANDOIS and VALOIS. Isabel survived him and with the consent of her son the 3rd Earl gave the church of Dorking to Lewes priory. She died probably before July 1147. [Complete Peerage XII/1:495-6, (transcribed by Dave Utzinger)]

Note: According to Ancestral Roots, Isabel preceeded William in death in 13 Feb 1130/31--not July 1147.
