Waves of Catholic emigrants, initially encouraged in the 1840s by Father Theodore J. van den Broek, emigrated from southern Netherlands to form communities in Wisconsin, primarily to Little Chute, Hollandtown, and the outlying farming communities. Whole families and even neighborhoods left for America. Most of these early emigrants were from villages near Uden, including Zeeland, Boekel, Mill, Oploo and Gemert. By contrast, many Protestant agrarian emigrants to Michigan and Iowa were drawn from Groningen, Friesland, and Zeeland; areas known for their clay soils.
