Edmund Beaufort, 2nd Duke of Somerset married before 1436 probably, abt 1425, Lady Eleanor Beauchamp, widow of Thomas de Ros, 9th Baron de Ros, daughter of Richard de Beauchamp, 13th Earl of Warwick and his first wife, Elizabeth de Berkeley, daughter and heiress of Thomas de Berkeley, 5th Baron Berkeley and Margaret de Lisle, 3rd Baroness Lisle.
When his eldest brother, Henry Beaufort, 3rd Duke of Somerset, was killed fighting for Lancaster in 1464 at the Battle of Hexham, the next brother, Edmund, succeeded to the Dukedom, and John became "Marquess of Dorset" and "Earl of Dorset", courtesy titles granted to the Beaufort heir-apparent or heir-presumptive.
He then fought under Somerset and Shrewsbury in 1439 and the Duke of York in 1441–2, when he was made captain of Alençon and knight banneret.
