When remembering America’s first ladies, there is a general assumption that these women were the wives of the presidents. This is not surprising since, with the exception of James Buchanan, all the presidents have been married men. However, several presidents were widowers or husbands of women who could not assume their duties. These men had to rely on women who were neither their wives nor their companions as stand-in first ladies with the primary duty of entertaining visitors to the White House. They included daughters Martha “Patsy” Jefferson Randolph, Martha Johnson Patterson, and Margaret Woodrow Wilson; nieces Emily Tennessee Donelson and Harriet Lane Johnston; daughters-in-law Angelica Singleton Van Buren and Priscilla Cooper Tyler; and sisters Mary Arthur McElroy and Rose Cleveland. They were real persons who each brought a unique experience to their work, which, unlike the service of their more famous married counterparts, has long been forgotten.
