Bricem Cox, husband of Nancy M. Bean, was difinately born 14 May 1821. I studied the picture of his tombstone under a high powered magnifying glass. It reads: 51 yrs 5 mos 5 dys. He was born in TN as the census shows. Brisom G. Cox listed as name on son's (Thomas Jefferson) marriage certificate. Also listed as Brisom G. Cox on daughter's (Nancy) marriage certificate.
Sorry for any confusion my first posting may have caused.
