On May 1, 1860, when she was about 21, Parker married
John Edward Bouligny, a recently elected congressman from Louisiana, in what
The Washington Star called "perhaps the most brilliant wedding that has ever taken place in the Federal metropolis." The event was attended by President
James Buchanan, several cabinet secretaries, and numerous members of Congress. Years later, the wedding was misidentified as the occasion when Buchanan learned of South Carolina's secession; however, that did not happen until December 1860. Bouligny was the only member of the Louisiana congressional delegation who refused to resign his seat when the state seceded, so the couple mostly remained in Washington during the
Civil War, living at her father's home. In May 1864, Bouligny died at the Parker family home. After Bouligny's death, she remained active in social and political circles in Washington, including raising funds for the completion of the
Washington Monument. In 1877, she married Australian politician and journalist
George Collins Levey, traveling with him back to Australia and his family home in England. Levey had been in the United States, representing Australia at the 1876
Centennial Exposition in Philadelphia, when he and Mary Elizabeth met. They spent their first year of marriage apart: Mary Elizabeth returned to Washington after the death of her mother, while Levey continued on to Australia. ==Author==
