"Edward of Salisbury, styled also Edward the Sheriff, whose parentage is unknown,[footnote (b) According to the Book of Lacock, he was the son of Walter le Ewrus, Earl of Rosmar, a fictitious person, and br. of Ceroid, Earl of Rosmar, b. in Normandy before the Conquest (Dugdale, Mon., vol. vi, p. 501). The nickname "le Ewrus" (= I'heureux, or the fortunate) was converted into "de Evreux" by later writers, with the result that the family has been given the name of Devereux and has been tacked on to the Norman Counts of Evreux (see the tabular pedigree given by Planche, Journal of the Brit. Arch. Ass., vol. i, p. 39; cf. Appendix G to this volume). For the exposure of this mistake see Herald and Genealogist, vol. iv, p. 149. "Rosmar" is an error for Roumare (Normandy), which was not a comte (cf. ante, vol. vii, sub Lincoln); but the statement that Edward was br. of Ceroid de Roumare, though apparently accepted by Nichols, Arch. Inst., Salisbury vol., 1849, p. 213, and in the 1st ed. of this work, is baseless.] was b. ante 1060,[footnote (b) As he was already sheriff in 1080.] it is said in England. [footnote (d) Dugdale, Mon. vol. vi, p. 50 1. His name* is English, but Edward was one of the English names adopted by the Normans before the Conquest (Round, Feudal England, p. 327).] He was sheriff of Wiltshire so early as Feb. 1080/1.[footnote (a) As Edward the Sheriff he attested a charter of Queen Maud for Malmesbury in Feb. 1 080/1 and a charter of the Conqueror and Maud for Holy Trinity, Caen, in 1082, as well as sundry royal notifications which may be of earlier or later date (Davis, Regesta, nos. 135, 149, 194, 232, 247, 267, 270, 283).] In 1086 he held in chief 33 manors in Wilts, as well as smaller estates in Surrey, Hants, Dorset, Somerset, Middlesex, Bucks, Oxfordshire and Herts,[footnote (b) Domesday Book, vol. i, passim. Most of his Wiltshire manors can be traced later in the possession of his descendants.] being styled in D.B. "Edwardus Sarisburiensis."[footnote (c) For the practice of a sheriff taking his name from the capital of his county, see Round, Feudal England, p. 168.] He survived the Conqueror.[footnote (d) As Edward of Salisbury he attested 3 notifications of William II, (?) 1087 (Davis, op. cit., nos. 292-94).] He m. ..., of whom nothing is known.[footnote (e) By her he had issue, besides his s. and h., a da. Maud, who m. Humphrey de Bohun II, at the instance (it is said) of William II (Dugdale, Mon., vol. ii, p. 67).]" [1]
