"People don't know how entertaining a study [genealogy] is. Who begot whom is a most amusing kind of hunting; one recovers a grandfather instead of breaking one's own neck—and then one grows so pious to the memory of a thousand persons one never heard of before."

(1) According to one account, the prisoner captured by John Giffard, before he was himself captured, was instead Alan la Zouche's brother William la Zouche (d. 1272), 23xG, but we've found no other mention of William being present at the battle.

(2), (3) Ralph Basset, who fought for the rebels at Evesham and was killed, was a son-in-law of Roger de Somery, who fought for the king and survived.

(4) Roger de Mortimer is known to have killed Hugh le Despenser at Evesham; some accounts state that he also delivered the deathblow to Simon de Montfort.

(5) "In 1323 miracles were said to be worked by his body, then hanging in chains at Bristol." [Richardson, Royal Ancestry]

(6) Probably, but not certainly, present at Crécy.

(7) Probably, but not certainly, present at Crécy.

(8) He appears in Shakespeare's Henry IV, Part I as "Sir Walter Blunt," transformed from a middle-aged man into a young one. His death at Shrewsbury is the occasion of Falstaff's bitter monologue about the uselessness of knightly honor.

(9) On the expedition to France in 1415, he was Master of the King's Horse for Henry V. He was at Agincourt with six men at arms.

(10) Described by the Oxford Dictionary of National Biography as a "landowner and gang leader" and "one of Suffolk's henchmen," he was a thoroughly bad man whose violence and cupidity flourished in the lawless conditions that led up to the Wars of the Roses. Following Towton he continued to fight on the Lancastrian side. After the battle of Hexham he was discovered hiding in a coal mine with 3000 marks intended to pay Lancastrian soldiers. He was taken to the Sandhills in Newcastle and summarily beheaded. Entertainingly, he is an ancestor of George Washington, among many others.
