Do you know the names of Mathias' parents? I am distantly related to Umbdenstocks from Alsace which was part of Germany from time to time. One Mathieu Umbdenstock was on the same ship as my great grandfather in 1847. Mathieu was born about 1847 in Alsace. My great grandfather settled in Downers Grove (Du Page county, Illinois) and then Lemont (Cook County, Illinois). Will gladly correspond and compare information.
