  • Notes 
    • From the Oxford Dictionary of National Biography:

      Mortimer, Roger (I) de (fl. 1054 - c. 1080), magnate, may never have set foot in England but was the progenitor of the Mortimer family whose importance in English history lasted until the male line died out in the early fifteenth century. His parentage is not certain, and different theories have been put forward to account for the evidence, in particular a charter attestation by a 'Roger, son of Ralph de Warenne', and the statements of the earliest genealogist of the family, Robert de Torigny, in the early twelfth century. Most plausibly Roger was the son of Ralph (I) de Warenne and his wife, BĂ©atrice, who is shown to have been a niece of Duke Richard of Normandy by the later statement of Archbishop Anselm that the Warennes and the dukes then shared an ancestor four generations back on one side and six on the other. That parentage would make Roger (I) de Mortimer a second cousin once removed of Duke William, the conqueror of England. In any case he was certainly related in some way to the ducal house.

      From Complete Peerage IX:266-7:

      Roger de Mortemer, Seigneur of Mortemer-sur-Eaulne in Normandy, was one of the leaders of the Norman forces at the battle of Mortemer in 1054, but having assisted the escape of one of the French prisoner, Ralph, Count of Montdidier, to whom he had done homage, he was exiled and his lands confiscated. He was afterwards reconciled to Duke William and some of his lands were restored to him, though not Moretmer, which had been given to his consanguineus William de Warrene; Saint-Victor-en-Caux thereupon became the caput of the Norman honour of the family. He is said to have founded the abbey of Saint-Victor-en-Caux. He was living in 1078 or later, but was dead in 1086, when his son Ralph appears in Domesday Book. He married Hawise (c).

      (c) Hawise and Ralph her son gave land in Mers in the diocese of Amiens to the abbey; in 1192 Theobald, Bishop of Amiens, confirmed this gift at Mers. The fact that Hawise held land at Mers in Le Vimeu explains the homage done by Roger de Mortimer to Ralph, Count of Montdider, and suggests that the marriage was earlier than 1054, the date of the battle of Mortemer. Since Hawise and her son join in this gift, she appears to have survived her husband.
