I have information on a William Karge family that emigrated from Germany in 1871. They came from somewhere around Hagenow, Mecklenburg-Schwerin and moved eventually to Faribault County Minn.
William was born 12 Jan. 1838 and about 1868 he married Anna Maria Dorothea Dahling. They had one child William August H. Karge born in Germany in August of 1869.
I have more information on this family.
