Henry Stewart, Lord Darnley
A kneeling figure of Lord Darnley can be seen on the monument of his mother Margaret Douglas, Countess of Lennox in the south aisle of Henry VII's chapel at Westminster Abbey. Her other sons and daughters are also shown as weepers around the tomb chest. This shows him in armour with a crown placed just above his head. Henry Stewart, Duke of Albany, known as Lord Darnley, was the second husband of Mary, Queen of Scots (whose tomb is in the same aisle as Margaret's). They married at Holyrood in Scotland on 29th July 1565 and Henry was declared King the following day. He was mysteriously found dead in February 1567 (possibly suffocated) and was buried in the vault at the abbey of Holyrood.
