I am also looking for information on Nancy, but you provided a little because I hadn't known before this that she'd been married before. I don't know her maiden name either but knew that Elisha had married at the very least three times and not two, first to Maranda Boone, then to Jane Bell and finally to Nancy.
I am linked through his second wife, Jane Bell, through their son Otha Bowman, who married Mary Caroline SOPER. She married twice the second time to my ancestor's brother, Abraham FRY.
Any other information would be greatly appreciated.
