List of First Lady of the United States firsts

This list lists achievements and distinctions of various first ladies of the United States.

It includes distinctions achieved in their earlier life and post-first lady service.

There have been forty-two official first ladies and forty-five first ladyships.

This discrepancy exists because some presidents remarried while in office and some were not married so had no official first lady.

Also note that first ladies not recognized by the National First Ladies' Library listing include Martha Jefferson Randolph, Emily Donelson, Sarah Yorke Jackson, Angelica Van Buren, Priscilla Tyler, Mary McElroy, Rose Cleveland, Mary McKee, and Margaret Woodrow Wilson.
