Still, Sina Williams(born: 1874) Sina Williams Still was a beauty culturist in Cincinnati, OH. Born in Midway, KY, she was the daughter of Henry and Mary Williams.
Sina Still completed a course in beauty culture in Louisville, KY and moved to Cincinnati around 1900. She established her business around 1916 using the Poro System developed by Annie Turnbo Malone. (During the Civil War, Malone's parents left Kentucky and settled in Illinois. See the Turnbo Family entry in the NKAA Database.) The Poro System was developed in Malone's Poro College in St. Louis, MO, where women were trained to become independent saleswomen of beauty and haircare products [source: Marcus Garvey Life and Lessons, edited by R. A. Hill and B. Bair, p. 406].
Sina Still was president of the Cincinnati Poro Club, which was founded and organized by Mrs. Callie Parrish in 1919. Still was also a member of the Household of Ruth and a manager of the Orphan Asylum in Cincinnati.
Sina Still was the wife of Louis (or Lewis) Still (b. 1870 in AL); the couple married in 1896. She had two daughters from her previous marriage.
