Research Notes:

A manuscript narrating the foundation of Rievaulx Abbey records that “Robertum de Roos” married “Sibillam de Valoniis”, by whom he was father of “Everardum de Roos”. The 1162/63 Pipe Roll names "Rob de Ross", with no further words and no payment, and on the following line "Euerard de Ross" paying £30/6/8 in Yorkshire. This unusual arrangement of the names, as well as the large payment, suggest that it represents a record of the death of Robert de Ros and the payment by Everard de Ros of the fine for his inheritance, which in turn suggests that Everard (assumed to be Robert’s son) had already reached the age of majority at that time. However, this dating appears impossible if Everard was the son of Sibylle de Valoignes, who is recorded as having three children by her third husband whom she married in [1181/82].... [The] best explanation for this apparent contradiction is that Everard was born from an otherwise unrecorded earlier marriage of his father. The Red Book of the Exchequer refers to "Everard de Ros cxii s i d" in Yorkshire in [1167/68]. ¹

------------------------------

Everard de Ros was a minor, and in ward to Ranulf de Glanvil when his father died. In the 12th Henry II [1166], this feudal lord held of the crown eight knight's fees, and in two years afterwards, upon collection of the aid for marrying the king's dau., answered 112s. for those which were "de veteri feoffamento," and 31s. 1d. for what he had "de novo." He m. Roysia, dau. of William Trusbut, of Wartre, in Holderness, and, at the decease of her brothers, s. p., co-heir to her father's estate, which estate was eventually inherited by her descendants, Lords Ros, her sisters and co-heirs having no posterity. They had two sons. This Everard de Ros must have been a very considerable personage at the period in which he lived, for we find him in the year 1176 paying the then very large sum of £526 as a fine for his lands, and in four years subsequently, £100 more to have possession of those which the Earl of Albemarle held. He d. about 1186 and was s. by his elder son, Robert "Furfan" de Ros. ²
