Sorry for the misspelling. It is Steinheim.
I do not believe that Charles and Carl are one and the same. My information from a couple of different sources show Carls dob a 11/11/1825.
He and his wife, Mary Manders, married in Iowa (Bellevue I believe) and lived in Dubuque, Holy Cross, and Luxemburg (the city in the US, not the country). They ended up in Caledonia, Mn. where my records show they both died
