Doris Lüneberg & Henry Kolm of WI & NE

I am looking for more information about the Kolm family that settled first in Middleton, Wisconsin and then moved to Schuyler, Nebraska in 1879. My great grandparents, Doris Lünebergand Henry Kolm, were born in Germany and emigrated to Wisconsin. They had 10 children. My grandfather, William Louis Kolm (b.1884 d.1956), and my father, Leland Bernitt Kolm (b.1911 d.1994), were born in Schuyler.
