Esther Morris was influential in Wyoming and considered the mother of woman suffrage in the state. She reportedly held a tea party at her house in September of 1869 and invited about 40 people as well as two opposing candidates for the first Territorial Legislature. Mrs. Morris put the candidates on the spot and asked that they both pledge that whoever should win would introduce and work toward passing a suffrage law for the territory. The winner kept his pledge. She also was appointed Justice of the Peace at South Pass City, Wyoming on February 14, 1870.
