Prince Philip's granddaughters Princess Eugenie and Zara Tindall named their newborn sons after him weeks before his death

• Prince Philip, the Duke of Edinburgh, died at 99 on Friday.
• Princess Eugenie and Zara Tindall named their sons after their grandfather just before his death.
• Both of the boys have the middle name "Philip."

Prince Philip, the husband to Queen Elizabeth II, died at the age of 99 on Friday. He was the longest-serving British consort in history.

Philip was reportedly recovering from a heart procedure at the time of his death after suffering from heart problems for some time.

The late prince lived an extraordinary life, from working in the royal navy to leading organizations around the world.

But for both Philip and the Queen, family was often at the center of their lives. At the time of Philip's death, the couple had four children, eight grandchildren, and 10 great-grandchildren.

And the most recent additions to the royal family actually pay tribute to Prince Philip.

In the weeks before his death, two of Prince Philip's granddaughters, Princess Eugenie and Zara Tindall, named their sons after him.

Both Eugenie and Tindall gave their sons the middle name "Philip" for their grandfather.

Princess Eugenie welcomed her first child on February 9, naming him August Philip Hawke Brooksbank.

Tindall, on the other hand, gave birth to her third child on her bathroom floor in March. Lucas Philip Tindall is happy and healthy, despite his dramatic birth.

It did not appear Prince Philip and the Queen were able to meet their youngest grandchildren before Philip's death. After the birth of Tindall's son, they released a statement saying they "look forward to meeting their 10th great-grandchild when circumstances allow" and that they were "delighted" by his birth.

But both boys will carry their great-grandfather's legacy in name, even if they never got to meet him.

Eugenie and Tindall's children aren't the only members of the royal family to be named after Prince Philip.

Both Prince Charles and Prince William have Philip as middle names: Prince Charles Philip Arthur George, and Prince William Arthur Phillip Louis.

Meghan Markle is expecting Prince Philip's 11th great-grandchild this summer. She announced she was having a girl in early March.
