Ralph Boteler was one of the barons who took up arms against King John and whose lands were seized in consequence, but, making his peace, he had restitution on paying 40 marks upon the accession of Henry III, in whose reign he was constituted a commissioner for collecting the fifteenth then levied in the counties of Warwick and Leicester, in the former of which shires, he was likewise a justice of the assize. He was s. at his decease by his son, Maurice Boteler.
