I saw a documentary a while back concerning suspected followers/believers of the Nazarene's teachings who escaped into some mountains or some such assumption. They had unearthed some sort of large dwelling and not far away a cave with scrolls in it which somehow suggested they were written by a sect dedicated to the Nazarene long before the concept of "Christianity". Unfortunately it didn't interest me enough that I payed much attention to it.
If I recall correctly it was on the History channel. I'll try to locate it and post a link here when I have the time.
