Lord Augustus FitzClarence (1 March 1805 – 14 June 1854), was the youngest illegitimate son of William IV of the United Kingdom and his long-time mistress Dorothea Jordan.
 Like his siblings, he had little contact with his mother after his parents separated in 1811.
Henry II (5 March 1133 – 6 July 1189), also known as Henry Curtmantle (French: "Court-manteau" ), Henry FitzEmpress or Henry Plantagenet, ruled as Count of Anjou, Count of Maine, Duke of Normandy, Duke of Aquitaine, Count of Nantes, King of England and Lord of Ireland; at various times, he also controlled Wales, Scotland and Brittany.
 Henry was the son of Geoffrey of Anjou and Matilda, daughter of Henry I of England.
 He became actively involved by the age of 14 in his mother's efforts to claim the throne of England, then occupied by Stephen of Blois, and was made Duke of Normandy at 17.
 He inherited Anjou in 1151 and shortly afterwards married Eleanor of Aquitaine, whose marriage to Louis VII of France had recently been annulled.
 Stephen agreed to a peace treaty after Henry's military expedition to England in 1153, and Henry inherited the kingdom on Stephen's death a year later.
