My Greatgrandfather was Claus Heesch. He came from Wilster and I beleive lived in the Chicago area for awhile before settling in Titonka, IA. Considering the family name and the location, I suspect that Margaretha and Claus were related somehow, if not siblings, cousins of some degree. I have not been able to find out info on Claus's family. He came to the USA in 1872 and was born about 1846.
