This is what Meghan Markle's surname will be when she marries Prince Harry

Quite a mouthful...

Ever since Prince Harry and Meghan Markle got engaged back last November, we've been trying to find out everything and anything about the royal wedding, and now the nuptials are just this weekend.

We already know that Prince Louis won't be attending the royal nuptials and it was just announced that Prince Charles would be walking Meghan down the aisle, as her father Thomas Markle is now unable to attend.

But who will be Meghan Markle's wedding dress designer? What will the Queen wear? And what route is Prince William going to go down with the best man's speech?

The questions are endless.

One thing we do know however is what Meghan Markle will likely change her surname to once she marries Prince Harry.

Meghan's full name at the moment is Rachel Meghan Markle, but one she ties the knot it's thought she will become Rachel Meghan Mountbatten-Windsor. Quite a mouthful, we know.

Royal historian Carolyn Harris spoke about this change in name to Town & Country, saying: 'Junior members of the royal family have the option of using the surname.'

It's common for descendants of Queen Elizabeth to carry the name Windsor as well as Mountbatten, reflective of Prince Philip's surname.

Queen Elizabeth made the change in surnames used in 1960, according to the official royal website.

'In 1960, The Queen and The Duke of Edinburgh decided that they would like their own descendants to be distinguished from the rest of the Royal Family, as Windsor is the surname used by all the male and unmarried female descendants of George V.

It was therefore declared in the Privy Council that the Queen's descendants, other than those with the style of Royal Highness and the title of Prince/Princess, or female descendants who marry, would carry the name of Mountbatten-Windsor.'

It is also likely that the Queen will grant Harry a royal dukedom on his wedding day, which will give Harry and Meghan the titles of Duke and Duchess - and most likely of Sussex.

Yep, all a tad confusing we know. Good luck filling out all the paperwork for your move over here, Meghan.
