Although Markle has not been on any official royal tours yet, she's already proven to be a natural when it comes to carrying out royal duties during her public appearances with Prince Harry.
If you know you're a diehard royalist and can rattle off Queen Elizabeth facts like no other, then you'll know that her birthday is on June 9.
Ashford Castle has paid host to royality many times over the years - King George VI and the Queen Mother stayed there in 1939.
The residence, which now houses Sandringham Estate offices, is said to resemble "three Merrie England pubs joined together, oozing charm and character", according to Metro. "I think that moment [for Harry] really kicked in when his brother, Prince William, of course, settled down with Kate Middleton", Nicholl said at the time.
Harry and Meghan will step out onto the terrace of the Queen's London home to honour her official 92nd birthday, which falls two months after her real birthday on April 21.

Markle and Harry tied the knot a few weekends ago inside St. George's Chapel at Windsor Chapel. On Wednesday, Kensington Palace confirmed to Country Living U.K. that Markle will arrive with the queen at Runcorn Station via the royal train. Over 600 lucky guests attended the gorgeous wedding, including a number of different celebrities and members of the royal family.
The duke founded the Invictus Games, staging the first tournament in London in 2014, followed by Orlando in 2016, and Toronto previous year - and event which was attended by Meghan.
