French Canadians, Scots, Métis and other continental natives (e.g. Iroquois) trappers arrived in the late 18th and early 19th centuries, soon to be followed by Catholic clergy. Some travelled as members of the Lewis and Clark and 1811 Astor expedition. Few stayed permanently such as Étienne Lussier, often referred as the first "European" farmer in the state of Oregon. Evidence of the French Canadian presence can be found in numerous names of French origin such as Malheur Lake, Malheur River, Grande Ronde, Deschutes rivers and the city of La Grande. Furthermore, many of the early pioneers first came out West with the North West Company and the Hudson's Bay Company before heading South of the Columbia for better farmland as the fur trade declined. French Prairie by the Willamette River and French Settlement by the Umpqua River are known as early mixed ancestry settlements.
