Prince Harry and Prince William both know the groom, Charlie van Straubenzee very well, having all attended Ludgrove Prep School together. The groom's older brother, Thomas van Straubenzee, is one of Princess Charlotte's five godparents and both Charlie and Thomas were ushers at Harry and Meghan’s Royal Wedding in May. It's no surprise then, that Prince Harry and Meghan were amongst the guests and that Prince Harry was reportedly Charlie's best man. What was surprising was the fact that neither Prince William, nor Duchess Catherine, attended the wedding.
