Well, to be fair, he only Googles his name so much because there is so much weird shit going on there- once he started to figure it out he occasionally just goes back to find other significant aspects and draw connections.

Name, birthdate, signs in the heavens, astrology markers, physical attributes, mental attributes, interests (vocational/hobbies), bloodline, repeated bizarre synchronicity patters within 'random' events- all a big 'check that box'

They had been doing a pretty good job of hiding shit from him, in fact, it is panning-out that this was a concerted effort for a (good?) reason. For some reason he either cannot find-out at all costs and/or must discover all on his own with no guidance from those in the know.
