@zound ,to determine the historical accuracy of a document you examine all mention to persons and places mentioned in this document ,That is what I'm referring to .Some archelogical evidence to that effect:
First it was the name of the Roman governor Pontius Pilate found in a monument in Caesarea, Israel, in 1961.
Then came the discovery in 1990 in Jerusalem of an ossuary, a burial box for bones, bearing the name of Caiaphas, the high priest who condemned Jesus. Just recently it appears the most spectacular of all archaeological finds relating to Jesus has surfaced.
Another ossuary has come to light, this one bearing the names of Jesus, James and Joseph, three of the most prominent people in the New Testament. The ancient Aramaic words inscribed on the limestone box state that it belonged to "James, son of Joseph, brother of Jesus."
