When President Donald Trump's wife, Melania, stayed in New York during the beginning of his presidency, some speculated that the President's daughter, Ivanka, might take on some of the traditional duties of the First Lady in Washington. Some worried this would be another break from tradition by America’s unconventional 45th president; however, there have been numerous other times in US history when the ‘First Lady’ has been a woman other than the president’s wife. Sometimes, it’s because the president is a bachelor or a widower; other times, the First Lady is too ill to fulfill her duties as hostess and appoints a substitute. Or, as often seemed the case in the 19th century and perhaps now, the president’s wife took one look at the job and said “No, thank you!”
