Hermsen Family in Wisconsin

I am searching for surname Hermsen.My Hermsens are decended from Gerardus Hermsen b:12/09/182, Holthees Netherlands, d:08/09/1884, Little Chute, WI.He married Elizabeth Guerts b: 09/02/1819 Boxmeer, Netherlands, d:01/13/1906, Little Chute, WI.
There are hundreds of people in this lineage. I have 300 Hermsens alone and have not yet identified half of them.They came to Little Chute Wisconsin because of a Catholic Priest that had started a church here.The whole town was ALL Dutch Catholic until just recently.

Any Hermsen information would be appreciated.
Sincerely
Jim Kandler
