Godfrey had no legitimate progeny, but his wider family had many descendants among the aristocracy of Europe, many of whom after his death made use of the swan as a heraldic emblem.
The Dunstable Swan Jewel made in about 1400 is presumed to have been intended as a livery badge possibly given to his supporters by the future Henry V of England, who was Prince of Wales from 1399.
In 1459 Edward's mother Margaret of Anjou insisted that he should give swan livery badges to "all the gentlemen of Cheshire"; the type and number are unknown.
[5] Henry Stafford, 2nd Duke of Buckingham, a descendant of the Beauchamps, of Eleanor de Bohun, of Thomas of Woodstock and of John of Gaunt, used the swan with crown and chain as his own badge.
Bohun swan supporters survive on the Easter Sepulchre monument of Hugh Luttrell (died 1522) of Dunster, in St Mary's Church, East Quantoxhead, Somerset.
A modern example is on the huge stone sculpted heraldic achievement of George Fownes Luttrell (1826–1910) above the new main entrance door to the castle,[9] built as part of his remodelling.
