Mary was the daughter of Thomas R. Lee, and wife of Theodore Frelinghuysen Cornell Demarest (married September 8, 1870, New York City).
Her mother died while she was an infant, and she was cared for by her grandfather and a Scotch nurse.
She spent most of her married life in Passaic, New Jersey, until they moved to Pasadena, California, in hopes of restoring her failing health.
