Looking for any information for the family of Martin Dohm born 1817 in Prussia, married Anna M and settled in Cross Plains, Dane Co, WI. He may have immigrated at same time as son Ferdinand. Ferdinand was born 11/1845 in Stommeln, near Colgne in Prussia and immigrated in 1872, married Gerdreth Unknown (born in Michigan) and also farmed in Cross Plains, WI. Other known children of Martin & Anna are Catherine 1848, Anna 1853, Marie 2/1857 (married Adam Maier), and Sibilla 1862. Thanks!
