The river is named after Saint Francis Xavier (1506–1552) by the Jesuits, who explored the region under the French regime, and after François de Lauzon.[2]
Geography
Its course is also unusual, as it flows from northeast to southwest to branch off, halfway through, and continue its course from southeast to northwest.
The river has long been traveled by Native Americans; particularly the Abenakis. The Indian Reservation of Odanak, which today has a population of about 400, has existed since 1670. The Fort Crevier was also built in 1687 by the river. A temporary Jesuit mission was established at Coös for the Abenaki living in the Connecticut River valley or near the Kennebec River. When the Abenaki mission Saint-François-de-Sales located on the Chaudière River moved to Odanak, the village took the latter's name, "Saint-François”. Odanak is located on the banks of the Saint-François River, about 10 kilometers east of lake Saint-Pierre. In 1805, an 8,000 acre reserve (32.4 kilometres (20.13 mi)) was granted for Indian refugees in Durham Township, near the present village of L'Avenir, as well as 2,722 acres (1,102 ha) (11 kilometres (6.84 mi)) in 1853 on the shore of Petit Lac Saint-François in the township of Coleraine.[3]
