From the granite Shores of Celtic Brittany to the Prairies of the American West

Our family’s journey is a epic story of Atlantic crossings, wilderness exploration, frontier commerce, and the shaping of North America.

Part I: From Breton Granite to the St. Lawrence Shore

The story opens in the mid-17th century in Landerneau, a bustling port town in Finistère, Brittany. Here, Jean Caouette and Marie-Geneviève Vallée raised their family along the tidal waters of the Élorn River. Deep in Brittany, life was tied to ancient traditions, but the transatlantic pull of New France beckoned. Their young son, Pierre-Joseph Caouette, made the life-altering decision to leave France, crossing the perilous Atlantic to settle along the rugged south shore of the St. Lawrence River at Cap-Saint-Ignace.

In New France, Pierre-Joseph built a new life from the ground up, clearing land and establishing a homestead. In 1693, he married Marie-Anne Gaudreau, the daughter of pioneer Gilles Gaudreau and Anne Delaunay—one of the courageous Filles du Roi (King’s Daughters) dispatched by Louis XIV to build a colony. Together, Pierre-Joseph and Marie-Anne raised a resilient pioneer family along the St. Lawrence, including their daughter Marie-Félicité Caouette.

Part II: Deep into the Upper Country

In 1730, Marie-Félicité Caouette married Joseph Mignier dit Lagacé, merging her Breton heritage with a lineage founded by a Carignan-Salières soldier. Their home in Kamouraska became the launchpad for a generation of trail blazers.

Their son, Jean-Baptiste Mignier dit Lagacé, inherited the untamed spirit of the St. Lawrence pioneers and turned his eyes west toward the Pays d'en Haut (the Upper Country). Entering the fur trade, Jean-Baptiste pushed far beyond the mapped boundaries of French Canada into the Missouri River basin. By 1794, operating under a Spanish trade license, he established a historic trading post near the mouth of the Niobrara River, forging an enduring trade alliance and family bond with the Ponca Nation.

The trade ran deep in the bloodline. His son, Jean-Baptiste Meunier dit Lagacé (fils), took up the paddle for the North West Company. As a homme du nord (Northman), he navigated the demanding canoe highways through the Great Lakes all the way to Rainy Lake (Lac la Pluie) and the Red River country, spending his life transporting furs and goods across thousands of wilderness miles.

Part III: Settlement, Migration, and the American Frontier

As the golden age of the fur trade waned, the family returned to the fertile river valleys of Quebec. Jean-Baptiste’s daughter, Marie-Emélie Meunier dit Lagacé, grew up surrounded by the oral histories of the western trade. She married Gabriel Pinsonneau, uniting two prominent voyageur lines.

By the mid-19th century, economic shifts pushed their daughter, Lucy Passino (Pinsonneau)—the proud granddaughter of two fur trade voyageurs—across the border into Northern New York. Adapting to their new American home, the family Anglicized their name to Passino, establishing deep roots in Clinton County.

Lucy’s marriage to John B. Brown brought the family line into the American mainstream. Her son, Abraham Lincoln Brown, born during the height of the Civil War era, carried the lineage into the 20th century, passing this remarkable heritage down to his daughter, Lydia Corinna Brown.

The Legacy

What began as a quiet life in coastal Brittany evolved into a sweeping North American narrative. Through seven generations, our ancestors navigated every major chapter of the continent's expansion—from French colonial pioneers and King's Daughters to high-country fur traders, North West Company voyageurs, and American homesteaders.
