Weis' "Ancestral Roots" (54:31) calls him Justiciar of Ireland. (178:6) adds that he was Lord of Offaly.

Walter de Burgh, by his marriage with the heiress of de Lacy, had been created Earl of Ulster. At this time he was the head of the great house of the De Burghs, and to such a pitch had arrived the feud between them and the Geraldines that, at a meeting during 1264 at Castle Dermond, Maurice FitzMaurice FitzGerald, assisted by John FitzThomas, afterwards Earl of Kildare, audaciously seized on the persons of the Lord Justice, Richard de Capella, Richard de Burgh, heir apparent of Ulster, of Theobald le Butler, and one of two other great partisans of the family of the de Burghs, and committed them to prison in the castles of Ley and Dunamaise. At length the attention of Henry III was drawn to the disturbed state of his Irish dominions. A Parliament was held at Kilkenny, by whose advice the prisoners detained by the Geraldines were released; and the king, recalling the present Lord Justice, appointed in his place David Barry of the noble family of Barrymore who, curbing the insolent ambition of the Geraldines, restored peace between the two rival houses.41
