Sulpicians set foot in what is now the U. S. as early as 1670 when Fathers Dollier de Casson and Brehan de Galinee from Brittany landed in what would later become Detroit, Michigan. In 1684 Robert de la Salle headed an ill-fated expedition from France to what is now Texas, taking with him three priests, all Sulpicians. These were Fathers Dollier de Casson, Brehan de Galinee, and Jean Cavelier, the explorer's older brother. This expedition ended in failure, and the vessel carrying the three Sulpicians was shipwrecked in what is now the state of Texas. Among the survivors were the three Sulpicians, two of whom returned to France on the next available vessel. The third, Dollier de Casson, decided to remain to catechize the natives. This, after all, was a major motive for his coming. He met with little success in this endeavor, however, and finally decided to return to France as had his companions. His missionary zeal unslaked, he thereafter soon found a vessel to transfer him to the Sulpician enterprise in Montreal, which was quite successful and has endured down to the present day.
