The naming of the newest addition to the royal family pays a touching tribute to both the Duke of Edinburgh and Mike Tindall’s father.
Zara and Mike Tindall have chosen Philip as their son Lucas’ middle name in honour of his great-grandfather, the duke.
The 99-year-old royal patriarch, who is Zara’s grandfather, returned home to Windsor Castle last week after having heart surgery and spending a month in hospital.
But the name is also inspired by Mr Tindall’s father, to whom the former England rugby player is very close.
Philip Tindall was diagnosed with Parkinson’s disease in 2003, and his son has been open about the devastating impact of the “nightmare” condition and his deterioration in recent years.
Mike Tindall has long campaigned to raise awareness of the disease.
It is not known why the Tindalls chose Lucas, but Mr Tindall revealed they only decided on the name after their third child was born.
He said on his rugby podcast before their choice was revealed: “We haven’t got a name yet, no. We’re still working on it.
“We’ve always struggled with that too. We’ve never picked one before they arrive.”
Latin in origin, Lucas is a form of Luke or Lucius, meaning “light-giving” or “illumination”.
Luke is the author of the third gospel of the New Testament.
In 2019, Lucas was the 25th most popular boy’s name in England and Wales, according to data released by the Office for National Statistics last year.
It has generally increased in popularity over the past two and a half decades, coming in at 169th place in 1996, and peaking at 17th in 2009.
Zara’s cousin Princess Eugenie also gave her son – August Philip Hawke Brooksbank – Philip as a middle name in honour of the duke.
The Tindalls’ eldest daughter is called Mia Grace, while their middle child is Lena Elizabeth.
Mr Tindall announced Mia’s name on Twitter in 2014, writing: “For everyone who has asked what our daughters name, it’s Mia Grace Tindall.”
Lena is pronounced Lay-na and Elizabeth is in tribute to the Queen.
A spokeswoman for the couple said at the time of Lena’s birth: “It was just a name they liked.”
