Charles Ertel, Minnesota, early 1900s
I am looking for any information on the origins of Charles Ertel. He apparently arrived about 1883 from Bavaria and married Mary Mertes in Minnesota, possibly Nicollet County.
They had four daughters - Theresa, Mary, Ida and Julie. I know that Ida married Olaf Nelson and they lived in Nicollet County, MN.
Any information on Charles' family would be appreciated.
