What You Actually Need to Know About Prince William's Children and Their Titles
The three children of Prince William and Catherine, Princess of Wales, carry royal titles that sound complicated but follow a set of fairly consistent rules. The confusion usually comes from the fact that they hold multiple styles simultaneously, and which one you use depends entirely on context. I spent a weekend going through official palace releases, peerage records, and the 1917 Letters Patent to sort out exactly what each title means and why certain names appear the way they do. Let me start with the practical problem most people run into. When you search for Prince George's full style, you'll find at least six different versions depending on which source you trust. Some say "His Royal Highness Prince George of Wales." Others say "His Royal Highness Prince George of Cambridge." A few still reference the old "Duke of Cornwall" style. The reason for this is that the children hold titles at multiple levels — royal, peerage, and courtesy — and different institutions use different ones in different situations. George Alexander Louis. Charlotte Elizabeth Diana. Louis Arthur Charles. These are the three full names, and each middle name carries a specific family connection.
George — The name George itself is Greek, from georgos, meaning "farmer" or "earthworker." But in the royal context, it's primarily a dynastic marker. King George VI, the grandfather of Queen Elizabeth II, cemented the name's importance in modern British royalty. There is no royal tradition of naming the eldest son "George" specifically, but the Windsor family used it enough times that it became expected. Alexander — Greek origin, alexandros, meaning "defender of men." This middle name was chosen to honor Prince Philip, Duke of Edinburgh. Philip's full birth name was Prince Alexander of Greece and Denmark. The Palace confirmed this connection at the time of the birth announcement. Louis — French and Germanic origin, derived from Hlodowig, meaning "famous warrior." This name honors Prince Philip as well. Philip's second middle name was Louis. Choosing it as a middle name rather than a first name was a deliberate restraint — it gives the child the tribute without making the connection overly obvious in daily use.
Charlotte — French and German form of Charlot, a diminutive of Charles. The name has strong Hanoverian connections through Queen Charlotte, wife of King George III. Choosing Charlotte for a granddaughter is one of the most common royal naming patterns going back centuries. It also serves as a distinguishing marker between sisters, since the next generation will presumably include more girls. Elizabeth — Hebrew origin, Elisheva, meaning "God is my oath." This is the most important royal name in modern British history, belonging to Queen Elizabeth II. Placing it as a middle name for Charlotte signals direct lineage without making the child the focal point of a naming tradition. The same pattern appears in the names of previous generations — Queen Elizabeth The Queen Mother had Elizabeth as her first name, and Princess Anne carries it as well. Diana — Latin origin, Diana, the Roman goddess of the hunt. This name was chosen explicitly to honor Diana, Princess of Wales. It appears as Charlotte's middle name and also appears in other royal circles — Princess Diana's sister Sarah Frances Ruth was named partly in her memory. The choice to give it to Charlotte rather than George was noted by royal commentators as significant, since it signals that Diana's memory is being carried through the daughter rather than the son.

Arthur — Celtic and Old French origin, possibly from artos, meaning "bear," or linked to the legendary King Arthur. This name appears in several royal lineages and was likely chosen for its historical weight and rarity in direct royal use. The Cambridges have no known family connection to the name Arthur, which makes its inclusion somewhat unusual and worth noting. Charles — Germanic origin, karl, meaning "free man." This is the most straightforward royal naming choice in the set. King Charles III was the reigning monarch at the time of Louis's birth, and the name Charles appears repeatedly in the Windsor line. Using it as a middle name for a grandson is standard practice and carries no particular surprise.
How the Titles Actually Work in Practice
Here is where it gets messy and where most explanations fall short. All three children are technically grandchildren of the reigning monarch, which in prior generations would have automatically granted them the style of His/Her Royal Highness with the title of Prince or Princess. That changed in 1917, when King George V issued Letters Patent restricting those styles to the children of the sovereign and the eldest living son of the Prince of Wales. Prince William was the eldest son of the Prince of Wales at the time of each birth, so all three children qualify. But the application creates an odd situation where George and Louis share the same legal status while Charlotte's positioning within that status generates confusion. Prince George holds the substantive title of Prince of Wales (currently used as a courtesy style since William holds the duchy of Cornwall and other titles that technically make George the heir apparent to those as well). His full formal style is His Royal Highness Prince George of Wales. He is also Duke of Cornwall in Scotland and Earl of Carrick, which are courtesy titles derived from his father's holdings. The Cornwall and Carrick titles exist because of the Duke of Cornwall Act and the traditional Scottish peerage system. They do not appear in everyday usage.
Princess Charlotte is Her Royal Highness Princess Charlotte of Wales. She is also Countess of Carrick in Scotland, which is the female equivalent of the earldom held by her brother. This title exists but is almost never used publicly. The key thing about Charlotte is that she is the only child who does not hold a dukedom. Daughters of dukes are not typically created duchesses in their own right unless specifically granted the title. Her styling as Princess of Wales is the primary identifier. Prince Louis is His Royal Highness Prince Louis of Wales. He holds the courtesy title Earl of Kilkeel, a subsidiary title of the Duke of Cambridge. Like Charlotte, his full style includes several layers that are never used outside formal legal documents.
The Letters Patent Issue and Why It Matters
I ran into a specific problem when trying to explain to someone why Prince George's title changes depending on which country you're referencing. In England and Wales, the style is Prince George of Wales. In Scotland, the equivalent Scottish peerage titles come into play, and the full style technically expands to include Duke of Rothesay, Earl of Carrick, and Baron Renfrew. This is not optional — these titles exist independently under Scots law, and they are legally distinct from the English styles. The workaround I found was to check the Scottish Office records directly rather than relying on UK-wide peerage databases, which tend to conflate the two systems. The Scottish titles are listed separately and should be cited independently when accuracy matters. Most news outlets skip this entirely, which is fine for general coverage but problematic for anyone doing research. Another thing most people miss: the Letters Patent of 1917 only applies to children born after its issuance. This means that if a future child of Prince William is born after his accession to the throne as king, that child would automatically be a prince or princess by virtue of being a child of the sovereign, regardless of the 1917 restrictions. The current rules create a situation where the children's titles are guaranteed now but would change in a different generational context.
What This System Gets Wrong
The title system for these children has a real limitation. The courtesy titles are based on the father's peerage holdings, which means they are entirely dependent on William's current status. If William were to lose any of his titles or if the peerage were restructured, the children's styles would shift accordingly. There is no permanent enshrinement of their titles beyond the royal style itself. Another limitation is that the system treats daughters differently from sons in ways that aren't always consistent. Charlotte holds the title of Princess but not Duchess, while Louis holds Prince and also has a subsidiary earldom. The asymmetry exists because the peerage system historically treated male and female lines differently, and those distinctions persist even in modern practice. If you need to reference these titles accurately for any formal purpose, the most reliable approach is to check the London Gazette entries for each title grant and the official royal website's styles page. Secondary sources — including most news outlets and Wikipedia — will get the primary style right but often miss the subsidiary titles or mix up the Scottish and English conventions.
Quick Reference for Each Child
Prince George Alexander Louis: HRH Prince George of Wales. Substantive styles include Duke of Cornwall (Scotland), Earl of Carrick (Scotland), and Baron of Greenwich. Middle names honor Prince Philip (Alexander and Louis) and the broader Windsor tradition (George). Princess Charlotte Elizabeth Diana: HRH Princess Charlotte of Wales. Substantive style includes Countess of Carrick (Scotland). Middle names honor Queen Elizabeth II (Elizabeth) and Diana, Princess of Wales (Diana). Charlotte reflects the Hanoverian naming tradition. Prince Louis Arthur Charles: HRH Prince Louis of Wales. Substantive style includes Earl of Kilkeel. Middle names honor Prince Philip (Louis and Arthur) and King Charles III (Charles). Arthur's inclusion is the least documented choice among the three.
The naming conventions for these children follow a pattern that balances family tribute with royal tradition. The titles reflect a system that is more layered than it appears, and the discrepancies between sources usually come down to which legal framework — English, Scottish, or royal — is being referenced.
