Princess Beatrice and Princess Eugenie may have grown up with the same royal titles, but their children are following very different paths when it comes to names, status and aristocratic tradition.

Neither sister has passed her British royal title down to her children.

Yet Beatrice’s daughters, Sienna and Athena, do have titles of their own — just not from the British Royal Family.

The difference comes from their father, Edoardo Mapelli Mozzi, and his aristocratic Italian background.

Meanwhile, Eugenie’s three children with Jack Brooksbank — August, Ernest and newborn Adelaide — remain untitled, despite all three having places in the line of succession to the British throne.

It creates an unusual contrast between two branches of the same family.

Beatrice and Eugenie’s children do not inherit their mothers’ princess titles

Beatrice, 38, and Eugenie, 36, are both princesses and use the style Her Royal Highness.

But those titles do not automatically pass to their children.

Unlike Prince William and Prince Harry, the sisters are not sons of the monarch and their children are not direct grandchildren of the current sovereign.

As a result, Beatrice and Eugenie’s children were not given British princely or princess titles at birth.

That includes Beatrice’s daughters Sienna Elizabeth Mapelli Mozzi, 4, and Athena Elizabeth Rose Mapelli Mozzi, 1.

It also applies to Eugenie’s sons August Philip Hawke Brooksbank, 5, and Ernest George Ronnie Brooksbank, 3, as well as her recently born daughter Adelaide Elizabeth Annina Brooksbank.

None of them are styled Prince or Princess.

But Beatrice’s daughters have Italian titles

This is where Beatrice’s side of the family becomes different.

Her husband, Edoardo Mapelli Mozzi, comes from an Italian aristocratic family.

He is the eldest son of Count Alessandro Mapelli Mozzi and is expected eventually to inherit the family’s ancestral seat, the 18th-century Villa Mapelli Mozzi in northern Italy.

Through that family tradition, Beatrice acquired Italian aristocratic styling when she married Edoardo in July 2020.

She became a “Contessa” and “Nobile Donna.”

Their daughters are also entitled to use aristocratic titles through their father’s family.

So although Sienna and Athena do not have British royal titles, they do have titles connected to the Mapelli Mozzi family.

That is not the case for Eugenie’s children.

Eugenie’s children remain untitled

Princess Eugenie married Jack Brooksbank in 2018.

Unlike Edoardo, Jack does not come from a titled aristocratic line that would pass a title to their children.

That means August, Ernest and Adelaide are not styled with either British royal titles or inherited aristocratic titles from their father.

Still, their lack of titles does not remove them from the royal succession.

All five of Beatrice and Eugenie’s children remain in the line of succession to the throne.

That distinction is important.

A place in the succession and possession of a royal title are not the same thing.

Beatrice is also stepmother to Edoardo’s son Wolfie

Beatrice’s family also includes Edoardo’s son from a previous relationship, Christopher Woolf, known within the family as Wolfie.

Now 10, Wolfie has appeared with the wider Royal Family on several occasions.

Beatrice has previously been described as his stepmother, while he has become part of the family unit she shares with Edoardo, Sienna and Athena.

His presence makes Beatrice’s household structurally different from Eugenie’s, but the title question still comes down mainly to inheritance rules through the paternal line.

Beatrice and Eugenie themselves remain princesses

Their own status is also notable given what happened to their father.

King Charles removed the former Prince Andrew’s royal titles and honors in October 2025 amid renewed scrutiny of his past association with Jeffrey Epstein.

But the decision did not strip Beatrice and Eugenie of their titles.

They remained Princess Beatrice and Princess Eugenie and continued to hold the HRH style.

Their positions were not altered by the action taken against their father.

That also meant the status of their children remained unchanged.

Their children are still in the line of succession

Although none of the children inherited British royal titles, they all remain in the succession order.

That includes:

Sienna and Athena through Princess Beatrice.

August, Ernest and Adelaide through Princess Eugenie.

Their position comes through their mothers’ places in the royal family tree, not through whether they hold formal titles.

That is why someone can be part of the succession without being called Prince, Princess, Lord or Lady.

Princess Anne made a different choice for her children

Beatrice and Eugenie are not the only members of the Royal Family whose children grew up without prominent royal titles.

Princess Anne chose not to give royal titles to her children Peter Phillips and Zara Tindall.

Anne later said she believed life had probably been easier for them as a result.

Speaking in 2020, she acknowledged that titles can come with disadvantages and said she believed raising them without that burden had been the right decision.

Peter and Zara have both gone on to build lives largely outside full-time royal duty.

Their example has often been cited as evidence that being closely related to the monarch does not necessarily mean using a formal royal style.

Edward and Sophie also kept HRH titles in the background

Prince Edward and Sophie, the Duke and Duchess of Edinburgh, took yet another approach.

Their children, Lady Louise Windsor and James, Earl of Wessex, were technically entitled to princely styles through their father.

But Edward and Sophie chose not to use HRH titles for them while they were growing up.

Sophie previously explained that she and Edward wanted their children to understand that they would most likely need to work for a living.

She said they could decide for themselves once they turned 18 whether they wanted to use the titles available to them.

So far, neither appears to have done so.

Lady Louise has continued using a simpler name

Lady Louise, now 22, recently graduated from the University of St. Andrews.

At her graduation in July 2026, she was announced as “Louise Mountbatten-Windsor,” rather than using a more senior royal title.

That was widely seen as another sign that she intends to continue with the relatively low-key style she has used throughout her life.

Her younger brother James, now 18, has similarly continued using the title Earl of Wessex rather than adopting a princely style.

When Buckingham Palace announced in August 2026 that James planned to attend the Royal Agricultural University, he was referred to simply by his existing title.

Titles do not always follow the obvious pattern

The British Royal Family can make the rules surrounding titles look deceptively simple from the outside.

They are anything but.

Some titles come automatically through descent.

Some depend on whether the person is a child or grandchild of a monarch.

Others are deliberately not used even when they are technically available.

And in Beatrice’s case, her children have inherited aristocratic status not from the British monarchy at all, but from their father’s Italian family.

That makes Sienna and Athena an especially unusual case.

They are descendants of the British monarch, members of the line of succession and daughters of a British princess — yet the titles they can use come from Italy.

Eugenie’s new baby highlights the difference

The birth of Adelaide has brought fresh attention to the contrast.

Eugenie’s daughter joins brothers August and Ernest without a formal royal or aristocratic title.

Meanwhile, her cousins Sienna and Athena occupy a similar place in the extended Royal Family but have inherited titles through Edoardo.

The children are all closely related.

They all descend from Queen Elizabeth II.

They all remain in the succession.

But the names and styles attached to them are different because of the families their mothers married into.

Beatrice and Eugenie’s children may grow up with very different public identities

For now, both sisters have largely kept their children away from intense public attention.

Neither family has raised its children as full-time working royals.

That may ultimately matter more than any title.

Still, the contrast is striking.

Beatrice’s daughters have no British royal styles but do have Italian aristocratic titles.

Eugenie’s children have neither.

And yet all remain part of the same royal succession.

It is a reminder that within the modern Royal Family, bloodline, title, rank and public role are no longer always the same thing.
