Saint Agatha developed as a farming community in the mid-nineteenth century as settlers moved outwardly from the St. John River around Frenchville. Alexandre "Menon" Ouellette was one of the first, such that Long Lake has also been known as "Lac à Menon." In 1889, Bishop James A. Healy assigned a French priest to the predominantly Catholic community, and a parish was founded.

A permanent church was built in 1890. The rectory (the priest's residence) was likely built or acquired around this time. The photograph shows both the old church (destroyed by fire in 1940) and, in the center, the rectory. Long Lake lies in the background.
