Josephine Louise Le Monnier was born in Baltimore on October 31, 1816 to Mary Sophia Waters and Alexander Le Monnier. She received her education in Baltimore and New Orleans. The latter city became her home at age fifteen, after the death of her mother. Other members of the family also lived in New Orleans, including her her older sister Eleanor Anne and brother-in-law William Henderson. There, Le Monnier met Warren Newcomb; the couple married in Christ Church Cathedral on December 15, 1845.
