I have some of these people in my ancestry. Ephriam Nathaniel Adams had a son, also Ephriam Nathaniel Adams b. Dec 16, 1816. He md. Frances Ellen Garver, a widow of John Carpenter, in Highland Co., OH. They removed to Washington Co., IA. I have a lot on the descendants of Ephriam and Frances Ellen Garver. Would be delighted to compare notes.
