Barbara Blackman O'Neil (September 3, 1880 – December 2, 1963) was an American suffrage leader in St. Louis, Missouri.
[5] She spoke in defense of Jane Addams and against the National Women Suffrage Association adopting an amendment that would prohibit any officer or member from participating in a major political party in 1912.
She was elected to the board of directors of College Suffragist, part of the National Women Suffrage Association, at that time.
[7] At the 1916 National Democratic Convention, when thousands of women took to the streets to draw attention to suffrage, O'Neil stood at the end of a "golden lane" of women representing states with full suffrage, where she was dressed as a "spirit of liberty.
[9][1] O'Neil and her husband moved from St. Louis around or after 1919, first to Europe, then to California, and eventually Cos Cob, Connecticut.
