Dyno's son, Ranulf Purcell, took his mother's name, de Broc, and was implicated in the assassination of Thomas Becket. Ranulf was excommunicated for theft of property of the Archbishopric by Becket, on Christmas Day, 1170, the traditional day of forgiveness. When Henry II, who was in Normandy, heard of this, he is said to have asked why none of his knights had rid him of "this troublesome priest". A few days later, four knights arrived at Saltwood, Ranulf de Broc's castle in Kent. After the murder, Saltwood was confiscated by Henry for De Broc's involvement in the murder. De Broc argued that the knights had lied to him and said Henry had ordered Becket be arrested.
