Some sources state that Aaron Burr, a longtime friend of Madison's since their student days at the College of New Jersey (now called Princeton University), stayed at a rooming house where Dolley also resided, and it was Aaron's idea to introduce the two. In May 1794, Burr made the formal introduction between the young widow and Madison, who at 43 was a longstanding bachelor 17 years her senior. A brisk courtship followed and, by August, Dolley accepted his marriage proposal. As he was not a Quaker, she was expelled from the Society of Friends for marrying outside her faith, after which Dolley began attending Episcopal services. Despite her Quaker upbringing, there is no evidence that she disapproved of James as a slaveholder. They were married on September 15, 1794, and lived in Philadelphia for the next three years.
