Ripples from La Prairie Voyageur Canoes: Chapter Nine: French Prairie and the Big Wedding, (1838

The Willamette Valley opened before them like a promise the mountains had never made. Long, open prairies stretched between stands of fir and oak, the soil deep and black, the winters mild compared to the upper Columbia. Former company men had already begun to take claims here, fencing small fields, raising wheat and potatoes, running a few cattle and horses. They called the district French Prairie for the language still spoken in most of the cabins and for the origin of the men who built them.

In 1838 François Rivet, now eighty-four, left the service of the Hudson’s Bay Company and came south with Therese and what remained of their household goods. Their sons Antoine and Joseph were already turning toward the same country. The old man who had once paddled for Lewis and Clark, survived the Bitterroot massacre, and interpreted through the Snake Country brigades now looked for a piece of ground that would not require him to move with the seasons.

They settled south of the new Catholic mission that would become St. Paul. The claim was taken in the informal way of the time—before any effective American land law reached the Oregon Country. A man simply chose unoccupied land, built a cabin, broke sod, and held it by presence and improvement. Rivet’s tract appears to have been shared in practice with Antoine and Joseph, the three men forming a small family cluster of fields and cabins within easy reach of one another.

That same year the Catholic Church arrived in force. Fathers François Norbert Blanchet and Modeste Demers came down the Columbia and began regular missionary work among the French-Canadian and Métis families of the Willamette. What they found were dozens of couples who had lived together for years according to the custom of the country—unions that were real in every practical and emotional sense, yet lacked the sacrament of marriage. The priests moved quickly to regularize them.

In January 1839, at the mission, a remarkable series of ceremonies took place. On a single day, and across the surrounding weeks, large numbers of long-standing couples were formally married in the Church. François Rivet and Therese Tête Platte were among them. After nearly thirty years together, after raising sons and enduring the deaths and distances of the fur trade, they stood before the priest and made the union canonical. Their sons Antoine and Joseph were baptized and entered in the registers as legitimate. The old freeman who had signed voyageur contracts with a mark now became, in the eyes of the Church, a husband in full standing and the head of a recognized Catholic family.

The mission registers from the years that followed show how thoroughly Rivet entered the life of the new community. His name appears again and again as godfather at baptisms and as witness at marriages. The younger French-Canadian and Métis families looked to the survivors of the old trade for continuity. Rivet, with his long memory and his quiet prestige as a man who had known Lewis and Clark and the early Columbia posts, became one of those elders.

Life on the claim was work of a different order. There were fences to build, fields to plow, livestock to tend. The skills of the trapper and interpreter were less useful than the ability to mend a harness or judge the right time to plant wheat. Yet the old habits of hospitality and mutual help remained. Neighbors borrowed tools, shared labor at harvest, and gathered for the feast days the priests introduced. The language of the cabins was still largely French; the children growing up on the prairie spoke a mixture of French, English, and the Indian tongues their mothers had carried from the interior.

Outside the small world of French Prairie the Oregon Country was filling with American settlers coming over the trail. Questions of government, land title, and sovereignty grew sharper each year. In May 1843 the famous meetings at Champoeg produced a provisional government. Rivet’s name does not appear among those recorded as voting on either side of the critical division. Whether he was absent, indifferent, or simply not counted remains unclear. What is clear is that the following year he took a public role. In 1844, at a meeting of the French-Canadian settlers, he served as one of three vice presidents. The gathering produced a memorial to the United States Congress—often called the French Petition—asking for protection against possible Indian conflict and for some clear sign of governmental interest in the Oregon Country. The old man’s name on that document placed him, late in life, among those trying to shape the political future of the valley he had chosen for his last home.

By 1845 François Rivet was ninety-one. Therese was still with him. Their sons were established on neighboring ground with families of their own. The great rivers that had defined his life—the Saint Lawrence, the Missouri, the Columbia—were now memories rather than daily realities. In their place was the slower current of seasons on the prairie: planting, harvest, the church calendar, the births and deaths of a settled community.

He had outlived empires, companies, and most of the men who had shared the early trail with him. What remained was the land, the family, and the quiet authority of a man who had simply refused to die when the country offered so many opportunities to do so.
