Let's start with John H. Imes. He was the son of Solomon A. Imes b. 1820 in Virginia and Mary Ann Gappen.He did marry Maria Keain. They had a daughter Emma Alice b. 1878 in Indiana. John had a brother James and a brother Marion or Mason. I could not find John in the 1920 or 1930 census.
I do believe that he went to Shelby Co., Ohio in a factory there in a rolling mill.
Did you find Helen in the 1920 or 1910 census?If so, where, I would like to look at them.
