Parish History

Catholic worship in Gilbertville goes back to 1856, when settlers built a small church from sawmill slabs. A larger church followed in 1868 but was destroyed by wind in 1874. The present parish was formally established in 1875 when newly ordained Fr. John Nemmers was appointed founding pastor on the very day of his ordination, December 19, 1875. He built the priest's residence, opened a school in 1876, and in 1892 brought the School Sisters of Notre Dame from Milwaukee to teach. Work on the present church began in 1888, and a new rectory was added in 1900.
