Birth order and titles explained
The order of birth determines placement in the line of succession and the specific styling of each child. All hold the title Prince or Princess of the United Kingdom and are styled as Royal Highness. Their territorial designation “of Cambridge” reflects the dukedom granted to their father at marriage. Succession protocol relies on birth date, not on gender, aligning with reforms enacted in 2013.
Succession position and legal context
The children’s positions are defined by birth date and regulated by the Perth Agreement (2011), which removed male-preference primogeniture for those born after 28 October 2011. As the eldest three children, George, Charlotte, and Louis occupy fixed ranks; a fourth sibling, if born, would follow. Names and styles are recorded in the official registry and announced through formal palace channels.
Common questions about names and ages
- Why are they called ‘of Cambridge’?
- How are ages calculated for heirs?
- Do names change if a sibling is born?
- Are school details ever confirmed publicly?
Reliable sources and how to verify
Key details—birth dates, names, titles, and succession order—come from official palace statements, registries of peerage, and constitutional documents. Independent royal correspondents corroborate these facts without relying on speculation. For ongoing verification, consult official royal communications and authoritative legal records pertaining to the line of succession.
Bottom line
Prince William’s children are Prince George (b. 22 July 2013), Princess Charlotte (b. 5 May 2015), and Prince Louis (b. 23 April 2018). They hold royal styles by birth, follow the line of succession by date of birth, and remain central to public interest in the monarchy while the household maintains disciplined privacy about day-to-day upbringing.
