I found an interesting article over a National Geographic documentary regarding Jesus. It goes into a bit of detail about the authenticity of the Shroud of Turin, claims of Stigmata (in which the wounds of Christ manifest in people without any apparent cause,) the idea of Jesus having a wife, and perhaps the idea that he may have left behind a bloodline. I'd be interested to see the documentary after reading about it, especially the bit about Stigmata, which is a phenomenon I've never heard of before.
