Lady Louise Windsor
The first child of Prince Edward and Sophie, Countess of Wessex, Lady Louise Windsor, 14, was born prematurely and with esotropia, a condition in which the eye is turned inward. Her vision was corrected by operation in 2013.

The descendants of Princess Margaret

Lady Sarah Chatto, 54, and husband Daniel Chatto, 61, also have two children, Samuel and Arthur. Samuel, 22, received some attention when he posted shirtless photos of himself on Instagram, while 19-year-old Arthur was a page to great-aunt Queen Elizabeth as a teenager.
Harry's more distant family
There are many more cousins in the House of Windsor, in part due to the fact that Queen Elizabeth's father, King George VI, had five siblings, three of whom had children. Some of the more prominent members of this part of the family include Prince and Princess Michael of Kent; Prince Edward, Duke of Kent and his wife, Katharine, Duchess of Kent; and Prince Richard, Duke of Gloucester.
