Duke of Westminster's baby faces major inheritance and title problem due to ancient rule

The Duke and Duchess of Westminster welcomed a baby girl into the world on July 27, with her birth announced in a statement from the proud new parents. The couple chose to announce the birth of their daughter, named Cosima, on the day that she was born.

The statement read: "The Duke and Duchess of Westminster are thrilled to announce the birth of their baby daughter. They have named her Cosima Florence Grosvenor." Cosima, whose name derived from the Greek word "kosmos", has been born into one of the wealthiest families.

The Duke of Westminster is said to be worth around £10 billion, and his extensive property portfolio is a major contributor to his wealth.

Following her birth, royal fans have now begun to speculate whether Cosima will be set to inherit her father's wealth and titles.

When the 6th Duke, Gerald Grosvenor, died in 2016, Hugh inherited his father's fortune and estate as the sole son and heir.

Speaking of Cosima, Wendy Bosberry-Scott, the editor of Debrett's Peerage and Baronetage, told HELLO!: "The dukedom of Westminster can only be passed down the male line, so it currently has no heir."

Confirming that Cosima is not set to inherit a title through her father, she added: "The Duke and Duchess [of Westminster] will need to produce a son for the titles to survive.

"Unless there is a change in the law, Lady Cosima will not inherit her father's titles."

As reported by HELLO!, a source close to the couple says they are focusing on being first-time parents.

They said; "The issue of titles and primogeniture is a matter for government and parliament, and isn't something the Duke and Duchess would comment on, certainly not at this stage. They're just looking forward to spending time with their daughter as a family."
