I descend from a John Heater/Heter, born March 18, 1813, in Ravenna, Portage County, Ohio. He married Sidney Jane Cartwright, in Abt. 1836, in Youngstown, Trumbull County (now Mahoning County), Ohio. He died on May 13, 1894, in Fairfield, Jefferson County, Iowa.
I wonder if my John is the son of your John Heater?
