Madame Marie Aioe Dorion Venier Toupin was the only female member of an overland expedition sent by Pacific Fur Company to the Pacific Northwest in 1810. Like her commonlaw first husband, Pierre Dorian, Jr., she was Mtis, with her mother from the Iowa tribe and a French Canadian father. She was also known as Wihmunkewakan , Walks Far Woman and Marie Laguivoise, the latter recorded in 1841 at the Willamette Mission and apparently a variation on Aiaouez, later rendered as Iowa.
