At birth, Victoria was fifth in the line of succession after the four eldest sons of George III: George, the Prince Regent (later George IV); Frederick, the Duke of York; William, the Duke of Clarence (later William IV); and Victoria’s father, Edward, the Duke of Kent. The Prince Regent had no surviving children, and the Duke of York had no children; further, both were estranged from their wives, who were both past child-bearing age, so the two eldest brothers were unlikely to have any further children. The Duke of Clarence and the Duke of Kent married on the same day in 1818, but both of Clarence’s daughters (born in 1819 and 1820) died as infants. Victoria’s father died in January 1820, when Victoria was less than a year old. A week later her grandfather died and was succeeded by his eldest son, George IV. The Duke of York died in 1827.
