1850 Census in Cincinnati, Ohio link should be added to profile https://familysearch.org/ark:/61903/1:1:MXQH-62Q. It shows his name as Kornmeyer, so that should be in Other Last Names, which can help with searches. Family list has wife Elizabeth, Mary, Theresa and Charles
1870 census he is listed as Coumire, so that is another name that should be in Other last Names.
I found 1860 when I had Coumire in Last name with Ohio, not Indiana for residence. Chas Conmire in Monro, Clermont, Ohio, so they were not in Cincinnati, but were not in Indiana yet. Family list includes wife Elizabeth, Mary, Clara, Franklin, and Augustus, so some of the family members are the same as 1850, parents born in Germany, so it matches. Another name to add to Other Last Names.
