THOMAS DE MULTON, son and heir, had probably succeeded his father before Michaelmas 1167. Between 1165 and 1171 he witnessed a charter of Conan, Earl of Richmond, at Richmond. In the last months of the reign of Henry II he took an active part in one of the violent episodes that marked the long contest between the houses of Croyland and Spalding for possession of the marshes. He was ill during the legal proceedings about the marshes in 1189.
He married Eleanor, whose parentage is not known, who died probably before October 1199. The date of his death is not known, but he was apparently dead in or before 1201. [Complete Peerage IX:398-9, (transcribed by Dave Utzinger)]
