John Davison Rockefeller 3D was the eldest son of John D. Rockefeller Jr. a philanthropist and heir to the Standard Oil fortune and Abby Aldrich Rockefeller. As the eldest of five sons (he also had an older sister), he was reared to assume his father's role as the steward of the family's commitment to social service through investment in worthy causes. The Rockefeller Baptist faith was reflected in his devotion to duty and serious purpose; his mother's warmth and good humor were expressed in his capacity for friendship. The Rockefellers maintained homes in New York City; Pocantico Hills in West Tarrytown, New York and Seal Harbor, Maine. The children enjoyed the rich opportunities for recreation available in these environments.
