The evidence

• “After a long and difficult journey, he arrived at Muskego, Racine county, Wisconsin, August 6, 1843. On his arrival there a congregation was organized—the first Norwegian Lutheran church in America, and on the 13th day of September, 1843, Clausen was called as their pastor. On October 18 he was ordained by Rev.”
