Seeking information on parents and wife of John B. Williford, born 1800 in North Carolina. He married a woman named Celia, also born in NC, unsure DOB. Their first child was Elmira, born in 1824, either in NC or TN. They had at least 7 children between 1824 and 1840, mostly in Illinois. John B. and Celia are on the 1840 US census in Saline Co, ILL where they lived until their deaths, Celia in 1850/51 and John B. in 1860. Family is well documented in Illinois, but have no idea of Celia's maiden name or John B.'s parents, nor the county where they lived. Many possible lines haven't proved correct. I'm stumped. I appreciate any help or suggestions.
