Margaret had for her share, Kendal Castle, with all Kendal which had been Peter's. She was married to Robert de Roos, the younger son of Robert Lord Roos, by his wife Isabel, daughter of the king of Scots. Robert's elder brother was William Lord Roos, of Hanlake. Margaret's husband, Robert Roos, died before her brother Peter. Margaret was alive in 20 Edward I, and her son William de Roos likely died before his mother since the inquisitiones post mortem is dated 3 Edward III, the same year that Margaret is shown to hold the manor of Melchanthorp. She had a grandson, also named William de Roos, who in 3 Edward III obtained a charter for a market at Stavely and a yearly fair on the eve day and morrow of St. Luke the Evangelist. Thomas de Roos was the son of William de Roos, and he died in 14 Richard II.
