Robert de Brus, 4th Lord of Annandale

Robert de Brus, called the Noble, was the fourth Lord of Annandale (c. 1195–1245), son of William de Brus. About 1219 he married Isobel of Huntingdon, daughter of the Earl of Huntingdon and a descendant of King David I.

The match brought him Essex manors including Writtle, and later supplied his great-grandson Robert the Bruce with his claim to the Scottish crown. He died in 1245 and was buried at Gisborough Priory, succeeded by his son Robert.
