Robert had the same name as both his uncle and his grandfather. His uncle died before becoming Lord of Annandale, and therefore his father, William, inherited the title, becoming 3rd Lord of Annandale. Robert married ca. 1219 Isobel of Huntingdon, the second daughter of David of Scotland, 8th Earl of Huntingdon, by which marriage he acquired the manors of Writtle and Hatfield Broadoak, Essex in England.Richardson, Douglas, Magna Carta Ancestry, Baltimore, Md., 2005, p.731-2, They had two sons and one daughter: Robert de Brus, 5th Lord of Annandale, married firstly Isabella de Clare, with issue; married secondly Christina de Ireby, without issue.
