Roger de Beaumont; Seigneur (feudal Lord) of Beaumont, Pontaudemer,Brionne and Vatteville, Normandy; married Adeline, sister of Hugh Countof Meulan and daughter by his 1st wife of Waleran Count of Meulan.[Burke's Peerage]
---------------------------------------
The well-known Roger de Beaumont held Sturminster Marshal, Dorset, in1086; it descended to the counts of Meulan through Roger's eldest son,Robert count of Meulan. That Roger took his name from Beaumont is a partof the general history of Normandy. It follows that Roger's descendants,the counts of Meulan, the Earls of Leicester, and the Earls of Warwick,all derive from Beaumont-le-Roger. [The Origins of Some Anglo-NormanFamilies]
