Descent from antiquity

In European genealogy, a descent from antiquity (DFA or DfA) is a proven unbroken line of descent between specific individuals from ancient history and people living today. No such proven lines exist. The ancestry of many living individuals can readily be traced back to the Early Middle Ages, but beyond that, all claimed lines to late classical antiquity have been shown to be speculative at best. Despite many ongoing efforts, no well-researched, historically-documented generation-by-generation genealogical descents from classical antiquity to modern persons of European or Eurasian descent are generally accepted in Western genealogical scholarship.
