Who is third in line to the throne among the Queen's family members?

Prince George is third in line to the throne as he is the eldest son of the Prince and Princess of Wales, William and Catherine. Following the changes introduced by the Succession to the Crown Act 2013, the line of succession now favors the eldest child regardless of gender. This means that Prince George, being the firstborn child, comes before his younger siblings, Princess Charlotte and Prince Louis, who are fourth and fifth in line respectively. As for the other family members, Prince Harry, while he holds a significant position in the royal family, is currently sixth in line, following Prince George, Princess Charlotte, and Prince Louis. Therefore, understanding the order of succession clarifies why Prince George is positioned as third in line to the throne.
