Lady Eleanor Talbot, also known by her married name Eleanor Butler, was an English noblewoman. She was a daughter of John Talbot, 1st Earl of Shrewsbury. After the death of Edward IV of England in 1483 it was claimed by Robert Stillington, Bishop of Bath and Wells, that she had had a legal precontract of marriage to Edward, which invalidated the king's later marriage to Elizabeth Woodville. According to Richard, Duke of Gloucester, this meant he, rather than Edward's sons, was the true heir to the throne. Richard took the crown and imprisoned Edward's sons, who subsequently disappeared.

John Talbot, 1st Earl of Shrewsbury, 1st Earl of Waterford, 7th Baron Talbot, KG, known as "Old Talbot", was an English nobleman and a noted military commander during the Hundred Years' War. He was the most renowned in England and most feared in France of the English captains in the last stages of the conflict. Known as a tough, cruel, and quarrelsome man, Talbot distinguished himself militarily in a time of decline for the English. Called the "English Achilles" and the "Terror of the French", he is lavishly praised in the plays of Shakespeare. The manner of his death, leading an ill-advised charge against field artillery, has come to symbolize the passing of the age of chivalry. He also held the subsidiary titles of 10th Baron Strange of Blackmere and 6th Baron Furnivall jure uxoris.
