Eleanor Grey

Lady Eleanor Grey (died before December 1503), was an English noblewoman, and the first wife of Sir John Arundell of Lanherne in Cornwall, "the most important man in the county", being Receiver-General of the Duchy of Cornwall. Their monumental brass in the church at St Columb Major in Cornwall was described by Dunkin (1882) as "perhaps the most elaborate and interesting brass to be found in Cornwall." Her father was Thomas Grey, 1st Marquess of Dorset. Lady Eleanor was an ancestor of the later Barons Arundell of Wardour.

Lady Eleanor Grey was a daughter of Thomas Grey, 1st Marquess of Dorset, and Cecily Bonville, Baroness Harington and Bonville, one of the wealthiest heiresses in England in the latter half of the 15th century. Elizabeth's paternal grandmother was Elizabeth Woodville, Queen consort of King Edward IV of England.

Eleanor had 13 siblings, including her eldest brother Thomas Grey, 2nd Marquess of Dorset (the grandfather of Lady Jane Grey, briefly Queen of England), who succeeded their father when he died in September 1501, when she was about four years old. Two years later, their mother, Cecily married Henry Stafford, 1st Earl of Wiltshire, which caused many quarrels over their inheritance.

Her maternal grandmother was Katherine Neville, Baroness Hastings who was direct descendant of Ralph Neville, 1st Earl of Westmorland and Joan Beaufort, Countess of Westmoreland, a daughter of John of Gaunt by his third wife, Katherine de Roët, making her a direct descendant of Edward III.
