Who was the first, First Lady of the United States not to be born in the United States?

First Lady of the United States (FLOTUS) is the title held by the hostess of the White House, usually the wife of the president of the United States, concurrent with the president's term in office. Although the first lady's role has never been codified or officially defined, she figures prominently in the political and social life of the nation. Since the early 20th century, the first lady has been assisted by official staff, now known as the Office of the First Lady and headquartered in the East Wing of the White House.

Louisa Catherine Adams (née Johnson; February 12, 1775 – May 15, 1852), wife of John Quincy Adams, was the First Lady of the United States from 1825 to 1829. Born in London, she was the first First Lady to be born outside the United States, or the preceding Thirteen Colonies, a distinction that would not be shared until 192 years later by Melania Trump.
