GEDCOMrhea (noun): a form of genealogical venereal disease, obtained by mindlessly adopting information found in unsourced family trees online. Symptoms include parents being only six years older than their children, people being married to two people or more at the same time (unless, of course, they're living in Big Love, Utah), and ancestors showing up in one or more censuses after they're declared dead.
Used in a sentence: "GEDCOMrhea can be avoided by confirming vital statistics with official documentation."
