 Agathe" was some decades earlier, when the Roman Catholic Church organized the Red River colonies between St. Norbert and the United States border into the Parish of Sainte-Agathe.As that parish grew and split into numerous more manageable parishes, the parish containing Pointe-à-Grouette was renamed the Parish of Sainte-Agathe by Archbishop Alexandre-Antonin Taché in 1873; the town adopted the name at some time after that date.A church, a school, and eventually a convent were built at the townsite.
