There are sites that now take the Wikipedia approach to family trees, collaboration and crowdsourcing, and what you do is, you load your family tree on, and then these sites search to see if the A.J. Jacobs in your tree is the same as the A.J. Jacobs in another tree, and if it is, then you can combine, and then you combine and combine and combine until you get these massive, mega-family trees with thousands of people on them, or even millions.
Postoje stranice koje preuzimaju Wikipedijin pristup obiteljskim stablima, suradnjom i crowdsourcingom, a ono što vi radite jest da učitavate svoje obiteljsko stablo, a ove stranice tada pretražuju kako bi vidjele je li A. J. Jacobs u vašem obiteljskom stablu jednak onom A. J. Jacobsu  u drugom obiteljskom stablu te, ako je, možete to udruživati, udruživati, udruživati i udruživati dok ne dobijete ova ogromna, mega-obiteljska stabla s tisućama ljudi u njima, ili čak s milijunima.
