Simpson was an American socialite and the wife of the Duke of Windsor, the former British King Edward VIII (Prince Harry’s great uncle). Their intention to marry and her status as a divorcée caused a constitutional crisis that led to Edward’s abdication in 1936. The couple married on June 3, 1937, at the Château de Candé in France. No member of Edward’s family attended.
(Before tying the knot with Harry in 2018, Meghan was married to film producer Trevor Engelson from 2011-2013.)
