Roman Catholic
;)
The Roman Catholic missionaries, like the other denominations, visited the Peace River country without setting up permanent missions for several years.
Father Bourassa was the first Roman Catholic missionary in the Peace River country, when he visited Lesser Slave Lake in 1846 and 1847. In 1856, both Father Lacombe and Father Thibault traveled to the Peace country.
Fort Chipewyan was chosen for a Catholic mission in 1849 by Father Alexander Taché. Father Henri Faraud became the first resident priest with the Roman Catholic Nativity Mission that was dedicated in 1851.

Father Faraud became the Bishop of the Athabasca-McKenzie diocese in 1867. Father Tissier and Father Faraud went to Fort Dunvegan. Father Faraud then went on to Fort St. John and was the first missionary to visit the Dunne-za First Nations.
Father Tissier was based at Fort Dunvegan from 1867 until 1883 when he became very ill. Father Grouard took his place. Father Grouard learned the Athapaskan, Cree, and Slavey languages and took on the lifestyle of the Dunne-za over his nearly 70 years of service in the north. This made him one of the most effective missionaries in the Peace country.
Father Grouard traveled to Grande Prairie in 1883 to become the first Roman Catholic missionary in the area. He visited Saskatoon Lake and several Métis communities.

In 1883, Father Husson started building a church at Fort Dunvegan with logs from upriver. The church was completed in 1885.
Father Lacombe visited the Lesser Slave Lake area in 1870. Fathers Rema and Dupin established a permanent mission at Lesser Slave Lake in 1871. In the following years missions were established at Sturgeon Lake (1884), Fort Vermilion, Fort St. John (1890), Spirit River (1891), and Flying Shot Lake (1899).
The work of the missionaries played an important role in preparing the way for the settlers that would come to the Peace River country later.
