[QUOTE=AcuteEnigma;620508...Seriously, though, anything more than 2000 years old is extremely suspect.[/QUOTE]

Not quite that far. Nothing more ancient than Charlemagne's ancestry is reliable, and I think that can be traced to Pippin I in the 500's CE, some 300years before his time. (Or is St Arnulf of Metz his earliest known ancestor?) There are those who claim that Charlemagne descends from the earlier Merovingian dynasty through a great grandmother, Bertha, but this is controversial.
