Meghan Markle is a real charmer, especially when it comes to winning over her future in-laws.

As the world already knows, Queen Elizabeth is a fan of her grandson’s future wife, as evidenced by the fact that she gave her royal blessing for their May 19 union. However, Prince Harry’s grandfather, Prince Philip, was allegedly harder to please.

Though Markle spent plenty of time with the entire royal family during her Christmas vacation at Sandringham and was spotted making public appearances alongside Queen Elizabeth II at the Commonwealth Day service at Westminster Abbey, she had to work to win the approval of Philip. But, according to the Express, she eventually did, thanks to a little sleuthing into his family’s past.

“The Duke of Edinburgh really got on with her,” a source revealed to the Express. “The reason he liked her was because she was very bold.”

According to the source, Markle showed her “boldness” by investigating Philip’s rather lengthy royal ancestry and sharing her findings with the Prince himself.

“Meghan asked a lot of questions, about Philip’s side of the family and his connection to Greece,” the source said.

And in case you were unaware, or ever plan to meet Prince Philip and want to impress him too, it’s key to know that Philip was born in Corfu, Greece, and was part of both the Danish and Greek royal families. However, tread lightly, because it could become a touchy subject.

"Prince Philip doesn't like Greece, because they put his father [Prince Andrew] on trial, and he might have been executed," royal historian Hugo Vickers told the BBC in 2012 ."In 1922, they all had to flee."

Still, Markle’s keen interest in her soon-to-be family appears to have worked as according to the Express source the two were heavily “involved in the conversation." So next time you’re hoping to impress your partner’s family try what Markle did and ask a few questions about their family’s past. Or, make it a bit more fun by ordering the entire group an ancestry kit that helps you plan a vacation based on your DNA history. The family who spits in tiny cups to test their DNA together stays together, right?
