Dear Cindy, I have an Ellen Bell and Joe Mattix in my database. The dates are about right although I don't have any for Ellen. But I do for her sisters and brothers as well as her parents and grandparents. They lived in Preble and in Darke county, Ohio. I am researching a Bell family in Preble county. Chances are Ellen's first name could have been Lucinda. Ellen's siblings were born between 1848 and 1855. Please contact me to compare notes.
