Old deeds or surveys taken in metes and bounds states may have individuals listed besides the grantors, grantees, and witnesses. There may be individuals listed with “cc” or “cb” listed after their name. Chain carriers or chain bearers helped the surveyor by carrying the measuring chain. These individuals generally had to swear an oath, had to be of legal age, and some times were relatives of the surveyor.
“CC” on an old deed does not mean “Carbon Copy.” [That was an attempt at humor.]
