Note:
Robert de Willoughby, 1st Lord (Baron) Willoughby de Eresby, so created 26 July 1313 by writ of summons to Parliament made out to "Roberto de Wylghby" (ie. Willoughby) alone, the addition of "de Eresby" not occurring till the 1350-Jan 1370/1 Parliament of Edward III, and then only in the period 1350-60, presumably because a similarly named personage, Richard de Willoughby (a descendant), was also called to that Parliament, the next version of the title to include the suffix "de Eresby" occurring in 1580 (when the 2nd Baron Willoughby of Parham was sitting in Parliament), the Barony from then on being held with superior peerages till 1870 but referred to in the declaratory patent of 18 March 1780 as "Willoughby of Eresby" and only as "Willoughby de Eresby" from the 1871 termination of the abeyance onwards, though for conveniance's sake this form has been adhered to throughout this article; born c 1250-60; campaigned against Scots, being present at Siege of Carlaverock 1300; married by 1303 Margaret, daughter of 1st Lord (Baron) Deincourt, and died just prior to 25 March 1316/7. [Burke's Peerage]

BARONY OF WILLOUGHBY OF ERESBY (I) 1313
ROBERT DE WILLOUGHBY, son and heir, born circa 1250-60, had a protection, going to Scotland with his great-uncle, the Bishop of Durham, 12 June 1298; was often summoned against the Scots, 1300-15; and took part in the siege of Carlaverock, July 1300. He is said to have been granted the manor of Eresby by his grandfather, John Beke, in 1301-02. He was summoned to Parliament from 26 July 1313 to 26 November 1313, by writs directed Roberto de Wylghby, whereby he is held to have become LORD WILLOUGHBY. On 16 October 1313, as a follower of Thomas of Lancaster, he was pardoned for his activities against Gavaston.
He married, in or before 1303, Margaret, daughter of Edmund (DEINCOURT), 1st LORD DEINCOURT, by Isabel, daughter of Sir Reynold DE MOHUN, of Dunster, Somerset. He died shortly before 25 March 1317. She died shortly before 18 October 1333. [Complete Peerage XII/2:657-8, (transcribed by Dave Utzinger)]
