• Background Information. ¹³⁵⁶
Roos was for long held in demesne by the Ros or Roos family, which is believed to have been named from its estate there. The first known member was Peter de Ros (probably d. by 1130), whose son Robert succeeded c. 1158 to Helmsley (Yorks. N.R.); the family took the title Baron Ros of Helmsley in the late 13th century. The estate in Roos was mentioned in 1202, when another Robert de Ros held land there of Herbert de St. Quintin [Yorks. Fines, John, pp. 76\endash 7]. At the death of Robert's grandson Robert in 1285 it was described as the manor of Roos. Part of the manor, including 1 carucate and 3¼ bovates of demesne land and evidently extending into Burton Pidsea and Tunstall, was held of the king as successor to the count of Aumale as 1 knight's fee; the remaining 4 carucates were held of the St. Quintins [Cal. Inq. p.m. ii, p. 345]. In 1301 a grant of free warren was made to William de Ros, who was named as sole lord of Roos in 1316 [Cal. Chart. R. 1300\endash 26, 21; Kirkby's Inquest, 304].
