Baron Grey of Ruthyn
The title of Baron Grey de Ruthyn (sometimes spelt Ruthin) was created in the Peerage of England by writ of summons in 1324 for Roger Grey, a son of John Grey, 2nd Baron Grey of Wilton. It has been abeyant since 1963. The Ruthyn branch of the Grey family based itself at Ruthin Castle in Wales.
The Bearers of the Great Golden Spurs, or Saint George's Spurs, the emblems of knighthood and chivalry, perform their service jure sanguinis, dependent upon descent from William Marshall, Earl of Pembroke, heir to his brother, John Marshall, who bore the Spurs at the Coronation of Richard I. in 1189. The Marshalls failed in the male line and the hereditary right descended in the female line through the family of Hastings to the Lords Grey de Ruthyn. The male line failed again and an equal right in the female line descended in 1911 to the Earl of Loudoun (Abney-Hastings) and Lord Grey de Ruthyn (Clifton).
