Beatrice Mills was raised around horses at her family's Livingston Mansion in Staatsburg, New York. Her father owned Thoroughbred racehorses in the United States and in France in partnership with Lord Derby. Beatrice's sister Gladys and her brother Ogden would establish Wheatley Stable that would become one of the preeminent Thoughbred racing and breeding operations in the United States.
