Could you help us with information regarding the following: Adam Bayer (born in Germany, August, 24, 1838) and Theresia Schultes (born in Germany, August 17, 1844 or 1845)? They married in Marquette, Michigan in the mid to late 1860's. They had 3 children born in Michigan: Robert, 1869; John, 1871; and Aulice, 1873. They then moved to Iowa. Adam worked in mining while in Michigan. I can find information concerning this couple after they moved to Iowa, but cannot find any information about them while they were in Michigan. Thank you.
