The biography of Robert le Waleys in Complete Peerage states [1]
Robert Le Waleys, s. and h.,(f) b. probably before 1158,(g) rendered account in Yorks for 2 m. in 1179, and held a mill of the Templars at Burghwallis in 1185.(h) He was Steward of Roger de Lacy, 11951209,(i) and deputy for him as Sheriff of Yorks, 1204-09.(j) His wife's name and parentage are unknown.(a) He d. circa 1218, before Feb. 1218/9.(b)
(f) He is called son of Henry in a confirmation-charter to Kirkstall Abbey
(Farrer, op. cit., vol. iii, pp. 232-33).
(g) On the assumption that he had attained his majority in 1179.
(h) Pipe Roll, 25 Hen. II, p. 23; 26 Hen. II, p. 67; B. A. Lees, Rec. of the Templars, p. 134. He paid scutage on ½ knight's fee in Yorks (Pipe Roll, 33 Hen. II, p. 91; 10 Ric. I, p. 37; 6 John, p. 190; Red Bk. of the Exch., pp. 62, 77).
(i) Farrer, op. cit., vol. iii, pp. 211, 213, 340. In 1211 he proffered 1000 m. in order not to be forced to render full account of the time when he was Roger's steward (Pipe Roll, 13 John, p. 33; Rot. de Finibus, p. 493). He witnessed many of Roger's charters (Farrer, op. cit., vol. iii, p. 211; Pontefract Chart., vol. i, pp. 35, 36; Sallay Chart., York Arch. Soc, Rec. Ser., p. 127).
(i) Pipe Roll, 7 John, p. 40; 8 John, p. 191; 9 John, p. 77; 10 John, p. 140; 11 John, p. 126.(a) Hunter, op. cit., vol. ii, p. 484, citing Dodsworth, says that his wife was Denise, da. and coh. of Robert the Poitevin. This is, however, unproved and the evidence suggests an earlier Waleys-Poitevin marriage. See p. 317, note "b" above.
(b) Rolls of the Justices in Eyre for Toris, 1218-19, Selden Soc, no 465. These cases were heard, Nov. 1218-Feb. 1218/9. In Trin. 1220 Joan, widow of Robert le Waleys, claimed dower in Cheddington, Bucks; but probably her husband was the Robert le Waleys living in East Anglia at Easter 1220 (Curia Regis Rolls, vol. viii, p. 351; vol. ix, pp. 172, 262; vol. x, pp. 94, 205).
