  2. only child; heiress presumptive to first cousin Richard II, and would be displaced in the succession by any children of the king.
  3. Lionel was 2nd son of Edward III and Philippa of Hainault.
  5. When Richard resigned his crown without issue on 29 September 1399, the rightful heir was Edmund Mortimer, 5th Earl of March, whose father Roger died the previous year. However, the throne was usurped by Richard and Philippa's first cousin, Henry Bolingbroke, an event that later precipitated the Wars of the Roses. As a result of her seniority in the line of succession to the throne of the Kingdom of England and her marriage into the powerful Mortimer family, her descendants eventually succeeded to the throne as the House of York under Edward IV.
