3 unusual facts about William de Mowbray


Charles Stourton, 26th Baron Mowbray

Another relative, William de Mowbray, was one of the barons who forced King John to put his seal to Magna Carta in 1215; as a direct descendant, Charles travelled to Washington, D.C. in 1976 with a parliamentary delegation that presented one of the four copies of the Magna Carta held by the British Museum to the U.S. Congress.

William de Mowbray

In January 1221, Mowbray assisted Hubert in driving his former co-executor, William of Aumâle, from his last stronghold at Bytham in Lincolnshire.

The ‘Progenies Moubraiorum’ makes Nigel predecease his father, and Nicolas and Courthope accept this date; but Dugdale adduces documentary evidence showing that he had livery of his lands in 1223, and did not die (at Nantes) until 1228.


Roger de Montbegon

According to the record publicized by the National Society Magna Charta Dames and Barons, Roger abandoned the sureties and therefore Roger de Mowbray (younger brother of William de Mowbray, another surety) was substituted for him; this probably explains Matthew Paris' alleged error.
