In 1119 Pope Callixtus II addressed letters to a group of Anglo-Norman landholders in the Welsh Marches, including Pain, accusing them of having appropriated the lands of the Diocese of Llandaff and ordering their return.
Pain gave lands to Llanthony Priory, helping to establish the endowment of that monastic house,[REF] although it is difficult to distinguish his gifts from those of Hugh de Lacy, as the monks of Llanthony grouped the gifts of both men together in their records [REF].
