Bainbridge House in Princeton
, New Jersey, the commodore's birthplace.
William Bainbridge was born in Princeton, New Jersey, eldest son of Dr. Absalom Bainbridge and Mary Taylor. His father, a loyalist during the American Revolution, served as a surgeon in the British Army and was convicted of high treason by the State of New Jersey and successfully filed for damages with the American Loyalist Claims Commission. William had two brothers: Joseph, who also became a Navy captain, and John T.; and a sister, Mary. He was raised by his maternal grandfather, John Taylor, Esq., of Middleton, New Jersey as his father left for England in 1783 and his mother remained behind due to her ill health (though his father returned to the United States and died in New York City in 1807).
