Founded in 1882 by area German, Irish, and Luxembourger families, St. John the Baptist Roman Catholic Church still serves Vermillion, MN. Despite being built wishes of the area's bishop, the parish soon grew. They received a part-time and then a full-time priest. The first church was replaced in 1912. Today, the community also includes an elementary school.
The church has a few records accessible via their website. Their "About Us" page links to a detailed history of the parish. Although the focus is on the priests more than the parishioners, you may find a mention of your ancestor if they were a church trustee or involved in fundraising. For most records, you will likely have to contact the church.
Find A Grave has a listing for the church's cemetery.
