Caroline Weldon (born Susanna Karolina Faesch; 4 December 1844 – 15 March 1921) was a Swiss-American artist and activist with the National Indian Defense Association.

That year, her mother was remarried to the exiled German revolutionary and physician, Dr. Karl Heinrich Valentiny, who ran a medical practice in Brooklyn.

Briefly residing with Stevenson in a rented apartment in Hoboken, New Jersey, she gave birth to a boy, she named Christie, in late 1876 or early 1877.

Weldon warned Sitting Bull that the Ghost Dance movement would give the government a pretext to harm him and to summon the military for intervention which would destroy the Sioux Nation.

She lived briefly in Kansas City with her nephew Friedrich William Schleicher, a school teacher, only to return eventually to Brooklyn.

[10] The poet and playwright Derek Walcott refers to Weldon and her life in his play The Ghost Dance and in his epic poem Omeros.

[citation needed] The film Woman Walks Ahead starring Jessica Chastain chronicles Weldon's life among the Sioux.

The people she helped rewarded her with a name: “Woman Walking Ahead.” But the four portraits of Sitting Bull she painted during that time were not the main reason she went out there, contrary to the impression some might get from watching the film.
