Sarah Polk Jetton Fall[b] (April 1, 1847 – July 22, 1924) was a wealthy Nashville socialite and philanthropist.

Sallie inherited the Polk estate upon Sarah's death in 1891, including several artifacts and papers from the late president which she later sold and donated to the Library of Congress.

In 1929 Saidee worked with the state of Tennessee to acquire the president's home in Columbia which was then opened to the public as a museum.

The president's wife Sarah mourned her husband's death deeply and became a recluse, rarely leaving her home Polk Place.

Judge John Catron would make the comment, "You are not the one Madam, to have charge of a little child; you, who have always been absorbed in the political and social affairs..."[9][6] But nonetheless Sarah still assumed guardianship, and brought in a nurse and maid to watch the young girl.

[19][20][21] In 1905 Sallie opened her own home in Nashville for social gatherings to exhibit the items she had inherited from Sarah and to tell the legacy of her great-uncle president Polk.

Shortly before her death she helped her daughter Saidee found the James K. Polk Memorial Association along with other Nashville women, with the main intent of preserving the president's legacy.

[26] In 1929 Sallie's daughter Saidee worked together with the state of Tennessee to purchase the only surviving private residence which the president lived in.
