Overview
Eleanor Maltravers, or Mautravers, ( 1345 – January 1405) was an English noblewoman. The granddaughter and eventual heiress of the first Baron Maltravers, she married two barons in succession and passed her grandfather's title to her grandson.
Origins
Her father was Sir John Maltravers, son of John Maltravers, 1st Baron Maltravers and his first wife Millicent. Eleanor's mother, a woman called Gwenthlian of unknown family, died in 1349, leaving Eleanor and her two siblings:
Henry (born in 1347), who died in infancy;
Joan (born about 1342), who married first Sir John Keynes and secondly Sir Robert Rous.
When her grandfather John died in 1364, his two heiresses were Eleanor and her sister Joan. When Joan died without leaving children, Eleanor herself became the sole inheritor of his title.
