Who do you think has the longest recorded genealogy?

I guessed wrong. :/

I would rather say it depends on which boocks you consider historically authoritative. If the Bible (OT and NT) is such a book, then Jesus, his genealogy go all the way back to David (then adds whatever genealogy David got (not much, wasen't he Sauls adopted 'son').
If you exclude the bible then Caesar, he came from one of the main patrician families in Rome.
I just ready your linked article, what a surprize :) I read the question wrong to think you meant the past genealogy of the persons named

In theory the Bible, but it is largely a codification of an oral tradition, much of which is symbolic. 

Jesus Christ Son of God. (Matthew 1:1-16; Luke 3:23:-38)

Another question would be, who has the longest genealogy based on true, authenticated records, rather than on folk lore, dogma and fable.
