[4] In 1902, in a quiet ceremony at Christ Church Cathedral, she married Guilford Dudley (1854–1945), a banker and insurance broker.

[4] A few years after being married, Anne Dallas Dudley became involved in the temperance movement as a supporter of alcohol prohibition.

In September 1911, Dudley, Daviess, Clark, and several other women[note 1] met in the back parlor of the Tulane Hotel and founded the Nashville Equal Suffrage League, an organization dedicated to building local support for women's suffrage while "quietly and earnestly avoiding militant methods".

[9] After serving as president of the local league for four years, Dudley was elected to head the Tennessee Equal Suffrage Association in 1915.

[12] Although the amendment was defeated, a later measure to give women the right to vote in presidential and municipal elections was eventually passed by the state legislature in 1919.

[9] In 1920, Dudley, along with Catherine Talty Kenny and Abby Crawford Milton, led the campaign in Tennessee to approve ratification of the Nineteenth Amendment to the US Constitution.

[9] Dudley's involvement in politics declined significantly in subsequent years,[12] with her efforts being focused on civic and charitable causes during the remainder of her life.

She was an active worker for the American Red Cross during World War II and later served as board chairman of the Association for the Preservation of Tennessee Antiquities.

[19] On August 26, 2016, as part of Women's Equality Day, a monument by Alan LeQuire was unveiled in Centennial Park in Nashville,[20] featuring depictions of Dudley, Carrie Chapman Catt, Abby Crawford Milton, Juno Frankie Pierce, and Sue Shelton White.
