Sorry, I misread your note, realize now you are looking for Hinrichs. There were 29 of those in the 1880 census for Iowa, none look to be in the Cedar Rapids area. Only nine were born in Iowa and lived in Iowa that year. They range in age from 5 months to 16 years; two lived in Lincoln and seven in Davenport. They were: Ludwig HINRICHS 1 <1879> Iowa Son Single White Male Lincoln, Iowa, IA Maria HINRICHS 4 <1876> Iowa Dau Single White Female Lincoln, Iowa, IA Anna HINRICHS 5 <1875> Iowa Dau Single White Female Davenport, Scott, IA Elisabeth HINRICHS 6 <1874> IOWA Dau Single White Female Davenport, Scott, IA Fred HINRICHS 5M <1880> Iowa Son Single White Male Davenport, Scott, IA Henry HINRICHS 3 <1877> Iowa Son Single White Male Davenport, Scott John HINRICHS 12 <1868> IOWA Son Single White Male Davenport, Scott, IA Mary HINRICHS 16 <1864> IOWA Dau NA White Female Davenport, Scott, IA Therese HINRICHS 3 <1877> IOWA Dau Single White Female Davenport, Scott, IA Hope this is helpful.
