John Beaufort, Marquess of Dorset and "Earl of Dorset", courtesy titles granted to the Beaufort heir-apparent or heir-presumptive. These titles were not recognized by King Edward IV, of the House of York. John had been in exile since 1461, first in Burgundy and then France. When Henry VI of Lancaster reclaimed the throne in October 1470, John returned with his brother Edmund. But a few months later, Henry was driven from the throne again, and the Lancastrians were on the run. John was killed in the Battle of Tewkesbury on 4 May 1471, while fighting beside Edmund, who was captured and beheaded two days later.
Henry Stafford (c. 1425 – 1471) Henry Stafford (c. 1425 – 1471) Sir Henry Stafford (c. 1425 – 4 October 1471) was the second son of Humphrey Stafford, 1st Duke of Buckingham and Anne Neville, daughter of Ralph de Neville, 1st Earl of Westmorland, and Lady Joan Beaufort. Henry's elder brother, also named Humphrey, died before their father, and so it was Henry's nephew, also Henry, who became the 2nd Duke of Buckingham. Stafford was the third husband of Margaret Beaufort, Countess of Richmond and Derby. The marriage was relatively long and successful and coincided roughly with the minority of Margaret's son, the future Henry VII
