They resided in Ohio. There is an Olive and J.M. Palmer in the 1880 Census of Bridgewater, Williams Co., OH. The transcription of this census at FamilySearch.com may have errors. It says that J. M. Palmer is a farmer, age 55, and born in NY. Both his parents were born in NY, too. Olive is 54 and it says she is born in OH. Her parents' birth states were either not readable or not listed. However, the two sons listed, Harley (11, OH, NY, NY) and Francis (9, OH, NY, NY), both show that their mother was born in NY. If Olive is not their mother, this would be okay. If Olive is their mother, then there is a mistake here. Olive should be listed as born in NY.
