there is no creast (coat of arms0 associated with the name Adcox and all "coats" belonged only to the holder, i.e a Baron, not to a family. There is a blazon associated with the spelling of, Adcock, the oldest form of spelling the Adcock/Adcox historical name. my third-great grandfathers where Joseph "Pappy Joe" Adcock and Asa"Pappy Asa" Adcock (prob. John Asa ,may be "pappy John"),Joseph's son Henry married Betsy, Asa's daughter. My gradfather was born Ezekiel Cloyd Adcocx, as where all his children, My grandfater was born Henry Thomas Adcox but reverted to the original spelling Adcock as did all his children, my historical seach has not accounted for the varied spelling. it's been spelled Adcock since 1197A.D.
