In 1419 she travelled to
Normandy with her sons to be with her husband there, leaving her daughters in the care of the Prioress of Dartford. Her husband died on 22 March 1421 fighting at the
Battle of Baugé,
Anjou, France. She was an executrix of his will alongside executors John Colvylle of Neuton, Cambridgeshire, knight, and Henry Merston of Westminster, clerk. In 1430 a book about the life of
St. Jerome was made for her by Symon Wynter of
Syon Abbey. Margaret retired to St. Saviour's Abbey, Bermondsey, London, where she died on 30 December 1439. The monument shows her lying in repose between her two husbands, which is extremely rare. Her husbands had been buried in the Trinity Chapel and were exhumed to be reburied alongside Margaret. ==Descendants==
