In page Margaret Hanmer:

"

After their homes at Sycharth and Glyndyfrdwy were burned in 1403, they lived, among other places, at Harlech Castle, which was taken in 1409 by the young Henry of Monmouth. Upon the fall of Harlech, Margaret was captured and imprisoned in the Tower of London with her daughter Catrin, another daughter, and Catrin's three daughters. Margaret's oldest son, Gruffudd, died in the Tower in 1411. Margaret survived the deaths of her two daughters and three granddaughters, but her own death is unrecorded. She is known to have been survived by her son Maredudd, who was alive in 1421, and by her daughter Alys, Lady Scudamore, of Monnington Straddle.[citation needed]
