I found Peter Gerhardt b. 1832, wife Catherine, children Catherine, John, Charles, and Margaret on the 1860 Waterloo Census. I'd like to know if this Peter is related to George N. Gerhardt, first husband of Justina Kaemper. Peter b. 1832 was living next door to my great grandfather, Frederick Meyer (who later married the daughter of George N Gerhardt) on the same 1860 census on page 105, so I'm thinking chances are good. I'd appreciate any help. And thanks again to my 3rd cousin's wife who found my Gerhardt first cousin's photo at a garage sale!
