Referring back to the ScreenRant report, Caroline Astor wasn’t the only Mrs. Astor in town. However, she claimed the title of the Mrs. Astor, a power play that placed her firmly in the upper, upper echelon of the New York City elite.

Caroline also had a great deal of influence with a club called the Four Hundred. It was basically the club to be in if you wanted to be considered the best of the best of New York society. Anybody who was anybody would kill for Caroline’s approval.
