Richard's English estates passed to his younger son William (I), [Chron. Mon. de Abingdon (Rolls Ser.), ii. 52] the king's Steward and an admirer and benefactor of Abbot Faritius and his monastery at Abingdon. By his marriage with Emma, the daughter and coheir of William de Falaise of Stogursey (Som.), William acquired large estates in several counties and an important position in the feudal hierarchy: he held his honor of Stogursey by the service of 25¼ knights [Red Bk. Exch. (Rolls Ser.), i. 224]. He was dead by 1130 and had been succeeded by his son William (II) de Courcy, who was probably dead by 1155, and by his grandson William (III) de Courcy, whose younger brother John conquered Ulster [Som. Arch. and Nat. Hist. Soc. lxvi. 104-6].
