The Great Plains Courier the founding of the Aubry Branch of the Santa Fe Trail.
François-Xavier Aubry was born December 3, 1824 near Quebec. In 1843 at 18, he left his home and moved to St. Louis, Missouri where he began working as a clerk for a French-Canadian merchant company.
In 1846, lured by the talk of trade, making money, and adventure on the Santa Fe Trail, he gave up his job as a clerk and became a full-time trader. By 1850, Aubry had traveled multiple routes with the goal of finding the shortest sand-free path that provided adequate water and wood. In 1851 he found it—establishing what became known as the Aubry Cutoff.
