Roger de Breteuil, 2nd Earl of Hereford

Roger de Breteuil, 2nd Earl of Hereford (1056 – after 1087), succeeded in 1071 to the earldom of Hereford and the English estate of his father, William Fitz-Osbern.

He did not keep on good terms with William the Conqueror, and in 1075, disregarding the King's prohibition, he married his sister Emma to Ralph Guader, Earl of Norfolk, at the famous bridal of Norwich.

Immediately afterwards, the two earls rebelled. Roger, who was to bring his force from the west to join forces with those of the Earl of Norfolk, was held in check at the River Severn by the Worcestershire fyrd, which the English Bishop Wulfstan, Walter de Lacy, and other Normans brought into the field against him.

On the collapse of his confederate's uprising, Roger was tried before the Great Council, deprived of his lands and earldom in 1075, and sentenced to perpetual imprisonment. He was released, with other political prisoners, at the death of William I in 1087.

Though Roger is not known to have married, he left two sons, Reginald and Roger. Living during the reign of Henry I of England, they were described as young men of great promise, but nonetheless were excluded from succeeding to Roger's lands. This has led to disagreement among scholars as to whether or not they were of legitimate birth.
