The birth of baby Lilibet could spark a surge in the number of people choosing the Queen's nickname for their children, royal commentators have predicted.
Prince Harry and Meghan Markle named their daughter Lilibet Diana after the monarch and Diana, Princess of Wales.
Royal commentators believe the name choice could encourage other parents to use "old school" baby names for their children too.
Molly Mulshine and Joe Drake, hosts of the podcast Royally Us, said Americans may choose to name Lilibet for their daughters.
Ms Mulshine told listeners: "I think there's going to be a big uptick in Americans naming their children Lilibet now. The question is how the Royal Family is going to feel about that.
"They might think it's a nice tribute or maybe not so much. I don't really know yet."
Mr Drake added: "I think old names are coming back. My niece is named Margaret, she was just born about a year and a half ago.
"Rather than like Mckenzie and Brittany we're starting to see those old names really come back.
"I think with the likes of Harry and Meghan naming their daughter Lilibet it's going to give us commonfolk a little bit more courage to name our kids something more old school."
Lilibet was born on June 4 at Santa Barbara Cottage Hospital in Santa Barbara, California.
She weighed 7 lbs 11 oz, a statement released on behalf of Harry and Meghan through their Archewell foundation said.
It continued: "Lili is named after her great-grandmother, Her Majesty The Queen, whose family nickname is Lilibet. Her middle name, Diana, was chosen to honor her beloved late grandmother, The Princess of Wales.
"This is the second child for the couple, who also have a two-year-old son named Archie Harrison Mountbatten-Windsor.
"The Duke and Duchess thank you for your warm wishes and prayers as they enjoy this special time as a family.”
Reports say Harry and Meghan are keeping the royal family up-to-date with pictures of their newborn daughter.
A photo was reportedly shared on the royals' WhatsApp group, where extended members of The Firm stay in touch, according to ET.
When Harry and Meghan announced Lili's birth, Buckingham Palace responded saying the family was "delighted".
They said in a statement: "The Queen, the Prince of Wales and the Duchess of Cornwall, and the Duke and Duchess of Cambridge have been informed and are delighted with the news."
