Prince Harry's cousin Princess Eugenie will also be taking a trip down the aisle this year. The princess became engaged to her longtime beau, Jack Brooksbank, in January, and the couple are set to marry on Oct. 12.
Princess Eugenie is the daughter of Prince Andrew and Sarah Ferguson, and she's currently eighth in line to the throne. Meanwhile, like Markle, Brooksbank is a commoner. He previously worked in the hospitality industry, and it's unclear what he will do after the royal wedding. The couple reportedly met during a ski trip seven years ago and have been dating ever since.
