I was just about to make the same point about Socrates as Novack has. I would have put it differently 
Your argument that stuff just wasn't written about unimportant folks in outposts of the Roman Empire is unsustainable by your own mythology. Joseph & Mary were going to do Sate admin, correct? Tax, Census, marriage, whichever you prefer. They weren't travelling all that way just to put a stone in a jar: as Novack says, both Roman and Jewish governments were big on record-keeping.
A humble birth attended by three kings/overlords/monks/noblemen would hardly have gone unremarked - oh, wait, it didn't, did it? The king of that entire territory, apparently, was so pissed off about this humble birth that he ordered a baby-killing spree. This, too, went unnoticed in Rome although they were certainly taking notes of his other crazed behaviour.
There are NO archaeological remains of a settlement at Nazareth during the time. None of his dad's tools, no money dropped by the flood of religious tourists you would have expected to be visiting, no jars or cookpots, no walls, not even a cesspit. Really, you wouldn't need written records - which there should be - to find evidence of a town that millions of people are so keen to find!
I find this immensely frustrating because it is interesting, imo, to seek the facts behind mythologies and to examine the cultural and philosophical messages behind their stories. When a whole raft of educated, intelligent and powerful people insist those myths are true despite weighty evidence to the contrary, such inquiries are pretty much strangled at birth. "Jesus said" is acceptable as an opening position, just as "Buddha said" or, for that matter, "King Lear said". But when that's stated as a bald, indisputable fact, it stifles all further discussion especially when Jesus very likely said something else that contradicts your quote.
Gah!
