Charlotte Smith (June 9, 1893 – December 9, 1936), known professionally as Lottie Pickford, was a Canadian-American silent film actress and socialite.

Born to John Charles Smith and Charlotte Hennessy, Lottie Pickford was named for her mother.

[2] After mistakenly believing she was a boy when first born, her father lovingly gave her the boyish nickname Chuckie.

[2] Their father, John Charles Smith, died in 1898 and eldest sibling Gladys took on responsibilities.

The rest of the family adopted the Pickford name by the time they began appearing in films.

[citation needed] Actress Linda Arvidson said Mary had claimed her sister was not pretty enough for films, and had done her best to keep her away from Biograph.

It was a vice film, with Pickford playing a prostitute, in stark contrast to her sister's image as "America's Sweetheart".

[12] Pickford starred in The Diamond from the Sky serial (1915) although, to her humiliation, she was only given the role after Mary turned it down.

Pickford again took several years' time off from acting before returning in a minor role in the 1924 film Dorothy Vernon of Haddon Hall.

"[13] Despite her reputation as a party girl, Pickford was considered to be down to earth, friendly, sweet, and unpretentious.

[16] On an unknown date in 1915, before the release of The Diamond from the Sky, Pickford quietly married New York broker Alfred Rupp.

[17] For unknown reasons, Pickford allowed her mother Charlotte to legally adopt her daughter, who was renamed Gwynne in 1920.

This arrangement lasted until Gwynne married radio announcer Hugh "Bud" Ernst in June 1939.

[22][23] Later that year, Pickford married a Pittsburgh society man named John William Lock.
