 In Cumbria, the powerful northern families and other, lesser, gentry, who were appointed Warden and deputy-warden included the Dacres, the Cliffords, the Musgraves, the Carletons, the Lowthers, the Ridleys and the Salkelds (many of whom were involved in, or encouraged, reiving themselves).It was not just the local magnates who might encourage the reivers – the English and Scottish governments did the same.The reiver light cavalry were useful to the Crowns in fomenting trouble against the opposite realm when required to do so.
