Prince Edward, Earl of Wessex, and His Family
In case we didn't say it enough times, the 1701 Act of Settlement existed when all of the queen's children were born, which is why her youngest son, Prince Edward, the Earl of Wessex, jumped his sister for his spot in the succession for the crown. Prince Edward, born in 1964, is ninth in line for the crown right now. He is married to Sophie, Countess of Wessex, and together they have two children.
Despite the fact that their daughter is older — Lady Louise Windsor was born in 2003 — her younger brother, James Viscount Severn, born in 2007, follows his father in line. That makes James Viscount Severn 10th in line and Lady Louise 11th.
