Prince Harry and Meghan Markle will tie the knot on May 19, 2018, and in celebration of their nuptials, it is tradition for Queen Elizabeth II to honor a royal union with new titles.

For instance, when Prince William and Kate Middleton married in April 2011, Her Majesty bestowed new titles upon them and they are now formally known as the Duke and Duchess of Cambridge. It is widely believed that Prince Harry and Markle will soon be known as the Duke and Duchess of Sussex.

But these are not the only monikers the newlyweds will receive, as it is also customary for the Queen to celebrate a royal marriage by granting a couple separate Scottish titles.

On the day of their nuptials, the Duke and Duchess of Cambridge were honored with the titles of the Earl and Countess of Strathearn, while Prince Charles is also known as the Duke of Rothesay in Scotland.

And according to several reports, it is widely believed that Prince Harry and Markle will become the Earl and Countess of Ross.

Wendy Bosberry-Scott, co-editor of Peerage and Baronetage, told the Press and Journal: 'The Scottish title Prince Harry receives is likely to be an earldom but there are very few clues here. One potential candidate is Ross, but this was last held by Charles I—who was executed in 1649—so it may well be considered unlucky.'

She continued, 'Dumbarton is another possibility but, at this point, it is merely speculation and many factors will have to be considered before a suitable title is chosen.'

But the decision is no mean feat, as Her Majesty must take into account other members of the Royal Family's rank before choosing new monikers.

Prince Harry and Markle's new Scottish titles will be announced on the day of their nuptials, so we'll just have to wait and see.
