He married Aveline, daughter of Sir John FitzGeoffrey, Justiciar of Ireland, by his wife, Isabel Bigod. In a royal order from Westminster in September 1247, Sir John FitzGeoffrey was charged by the King with seizing the lands of Walter de Burgh's older brother Richard, who had died. The de Burgh lands in Connaught were being held by John de Livet, likely the son of Gilbert de Lyvet, one of the earliest Lord Mayors of Dublin and Marmaduke de Eschales (Scales).
