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. Ancestry can readily be traced back to the Early Middle Ages, but beyond that, tracing to historical figures from antiquity is impractical due to insufficient documentation of the ancestry of the predominantly new royal and noble families of the period. Though the subject of ongoing effort, no well-researched, historically-documented generation-by-generation genealogical descents are known to exist in Europe.
