often called also the Victor of Flodden and is famous in history for that
battle. He married firstly Elizabeth Tilney, dauthter and heiress of Sir
Frederick Tilney, and widow of Sir Humphrey Bouchier, and married secondly
Agnes Tilney, a cousin of his first wife. A number of children by both wives
left descendants though the Ducal line comes through the first wife, Elizabeth,
as does also the Southern family in America.
