"

In 1930, she was presented at Court in London and was known as the deb (or debutante) of that year. Shortly afterward, she announced her engagement to Charles Guy Fulke Greville, 7th Earl of Warwick.[3] However, the wedding did not take place, for her head had been turned by Charles Sweeny, an American amateur golfer from a wealthy Pennsylvania family.[3] Her numerous early romantic escapades included an affair with the married Prince George, Duke of Kent.[4]
