Women in 1891, Stanton again brought up the authority women held in Iroquois culture. Chair of the Oregon Equal Suffrage Association (OESA), Eva Marie Dye, worked to get Sacagawea (Lemhi Shoshone) recognized as a national hero. Dye's work at creating a statue in Sacagawea's honor was central to much of the suffrage work in Oregon. The National American Women Suffrage Association (NAWSA) held its national convention at the unveiling of the statue in Portland in 1905. In August of 1909 suffragist Sophia Loebinger brought three Iroquois people to her speech at Palisades Amusement Park. She said, "I am reminded that many years ago the Iroquois tribes were ruled by women. They had their council of matrons and that is why their early government was so powerful." It was advertised that "Dawn Mist" and friends would march with suffragists in the Woman Suffrage Procession, on March 3, 1913, but Dawn Mist was not a real person. Instead, the Great Northern Railway had hired Native American women to perform as Dawn Mist, who acted as a publicity stunt for the Railroad company. Native American suffragists Cayuga physician, Peter Wilson, in 1866 urged members of the New York Historical Society to support women's right to vote. In Oklahoma, Native Americans and non-native suffragists met in 1904 to begin working with one another. The Oklahoma Woman Suffrage Association (OWSA) reached out to Chickasaw people in their own language, encouraging them to support women's suffrage. Marie Louise Bottineau Baldwin (Métis Turtle Mountain Band of Chippewa Indians) participated in a 1913 suffrage parade in Washington, choosing not to create a float using stereotypical images of Native women, but instead marching as "modern women." Baldwin also marched in the 1913 Woman Suffrage Procession in Washington, D.C. Native American women participated in suffrage demonstrations during the South Dakota state fair held in Huron. After the 19th Amendment was ratified on August 18, 1920, Zitkala-Sa (Yankton Sioux) reminded white women that Native American women still were not able to legally vote. Laura Cornelius Kellogg (Oneida) pointed out that white women had finally achieved what Native American women already possessed in their tribal communities. Zitkala-Sa lobbied the United States Congress to allow suffrage for Native American people in 1924. Lucy Nicolar Poolaw (Penobscot) and her sister, Florence Shay (Penobscot), fought for the right of Native Americans living on reservations in Maine to vote. In 1955, Poolaw became the first Native
