Prince Philip's granddaughters Princess Eugenie and Zara Tindall both paid tribute to their grandfather by naming their newborns after him, however, the Duke of Edinburgh was sadly never able to meet his great-grandsons.
Princess Eugenie and Jack Brooksbank, who married in October 2018, welcomed their firstborn in February, naming him August Philip Hawke Brooksbank.
In March, Zara Tindall and husband Mark welcomed their son Lucas Philip Tindall.
Due to coronavirus restrictions in the UK, it's believed both Eugenie and Zara were unable to introduce their sons to their grandfather before he passed away at the age of 99.
Prince Philip was a mentor to younger royals, who often turned to him over the years.
Eugenie once described him as "the rock" of the family.
During her appearance in the 2016 ITV documentary Our Queen at Ninety, Eugenie said, "I think Grandpa is incredible. He really is strong and consistent. He's been there for all these years, and I think he's the rock, you know, for all of us."
Prince Philip made a rare appearance last year at Eugenie's sister Beatrice's secret wedding to Edoardo Mapelli Mozzi.
Following Philip's death, royal historian Marlene Koenig has said she believes Beatrice will be feeling thankful he was able to attend the wedding.
"He was very much the grandfather," she told the Daily Express. "I think Princess Beatrice is now thinking her grandfather did get to go to her wedding.
"That Charles got to see him in the hospital. But none of his other children really that we know of have been able to see their dad.
"Having to break the news, how do you tell the young children that their grandfather is dead?"
The palace said in a statement: "It is with deep sorrow that Her Majesty the Queen announces the death of her beloved husband, His Royal Highness the Prince Philip, Duke of Edinburgh.
"His Royal Highness passed away peacefully this morning at Windsor Castle.
"Further announcements will be made in due course.
"The Royal Family join with people around the world in mourning his loss."
