Elizabeth Grey, 6th Baroness Lisle

Elizabeth Grey, 6th Baroness Lisle (c.1482/1484 – c.1525/1526[1]) was an English noblewoman during the reigns of Henry VII and VIII.

She is the Grandmother of the disputed Consort of England, Lord Guildford Dudley.

Elizabeth Grey was the daughter of Edward Grey, 1st Viscount Lisle (d. 1492) by his wife Elizabeth Talbot (d. 1487), daughter and eventual heir of John Talbot, 1st Viscount Lisle (1423–1453).

Her husband Arthur Plantagenet was created Viscount Lisle on 25 April 1523.

After Arthur Plantagenet's death in 1542, Henry VIII granted the viscountcy to Elizabeth Grey's eldest son by her first marriage, John Dudley, 1st Viscount Lisle, "by the right of his mother".
