Her siblings were Ellen Drexel (née Paul) Mills and Anthony Joseph Drexel Paul. Her father was a banker affiliated with the Drexel interests in Philadelphia and the Morgan interests in New York.^[2]

Her paternal grandparents were James William Paul and Hannah Clement (née Bunker) Paul. Her aunt, Mary Dahlgren Paul, was married to William Waldorf Astor (who moved to England and became the 1st Viscount Astor). Her cousins included Waldorf Astor, 2nd Viscount Astor (husband of Nancy Astor, the first woman to take her seat in the House of Commons), Hon. Pauline Astor (wife of politician Herbert Spender-Clay), and John Jacob Astor, 1st Baron Astor of Hever. Her maternal grandparents were Anthony Joseph Drexel and Ellen (née Rozet) Drexel.
