Charles Edgar Williford and Nancy Davis

I'm looking for information on Charles and Nancy Davis Williford.
I've looked on other genealogy websites and cannot get any farther than these two names. They had at least 3 girls Patsy and Rodeila are the only two I can remember at the moment. Rodelia married Perry Prough. Is there anyone who would help? I married their 5th Daughter, Carla. I'm trying to compile a family history and need the names if possible.

Thank you,
