My great-grandfather was Johann(3) Jakob Kronmiller and he was born in Nassig German on April 12, 1832.His father was Johann(2) Kronmueller and his mother was Anna Barbara Gotzelman. Johann's(2) father was Johann(1) Peter Kronmueller who was married to Anna Barbar Dosch.
After losing both his parents at the age of 16 (1948) Johann Jacob came to America with a younger brother (I haven't identified this brother yet). I'm not sure if they went directly to Indiana from Germany or how they came into the country. Jacob married Louisa (Ann) Harris in Ft. Wayne, IN on April 15, 1860.Their first 5 children were born there (1861-1869) and the last two girls were born in Kansas 1872 & 1874.I've not even tried to obtain birth certificates on the children yet as KS doesn't have any before 1910. The name was last spelled as Cronmiller when they passed away in Kansas.Does any of this tie into your work?
