Marie Aioe Dorion

"Madame" Marie Aioe Dorion Venier Toupin (ca. 1786 – September 5, 1850) was the only female member of an overland expedition sent by Pacific Fur Company to the Pacific Northwest in 1810. Like her first husband, Pierre Dorion Jr., she was Métis. Her mother was of the Iowa people and her father was French Canadian. She was also known as Marie Laguivoise, a name recorded in 1841 at the Willamette Mission and apparently a variation on Aiaouez, later rendered as Iowa.

Missouri It is likely that Dorion and Sacajawea knew one another. Peter Stark notes the similarities between the two women in his book Astoria: both women were originally based in the then-small settlement of St. Louis, and they were both wives of interpreters in the burgeoning Missouri fur trade. Dorion gave birth to another child near what is now North Powder, Oregon, who died several days later. Maria and the children stayed at a hut that the men had built processing the animals. Only Giles Le Clarc lived long enough to travel back to the hut and warn Dorion of the attack. and Marie Dorion Park, a Milton-Freewater, Oregon city park near the foothills of the Blue Mountains. The Dorion Complex residence hall at Eastern Oregon University is in La Grande. Her name is in the Senate chamber. St. Louis, Oregon, has a street named after her, Dorion Lane.

On May 10, 2014, the Daughters of the American Revolution held a service at Saint Louis Catholic Church dedicating a historical marker in Dorion's honor.
