McElroy presided over a number of events and honored former First Ladies Julia Gardiner Tyler and Harriet Lane, James Buchanan's niece and social hostess, by asking them to help her receive guests at the White House. McElroy's oldest daughter May and Arthur's daughter Nell often assisted. Her final reception took place on February 28, 1885, one week before the end of the Arthur administration: 3,000 people attended (including Adolphus Greely) and 48 daughters of officials and of the social elite assisted her.
