There are lots of accounts in Roman history as well as the gospels that were not included in the cannon. Here is quick overview of Barbelo, a book by Riaan Booyson.
Leading contenders for Josef and Mary are Marriam (1) the second wife of Herod the Great, and Josef (of the Flat Feet, of the Marble, etc, etc) his treasurer. Herod had killed Marriam's father and brother (since they were of royal blood, and a threat to his throne), and her mother asked Rome for help. They recalled him, and he ask Josef and another man to kill the women if he didn't make it back alive. The women managed to get that news, and when he got back from Rome, the shit hit the fan. Marriam refused sexual advances from him (she did already have two sons by him, that he had killed just before he died). Herod knew they had spilled the beans, but Josef's father in law was an important Roman politician, so he couldn't touch him, but the other dude was killed instantly.
Marriam and Josef had a brief fling, and she was with child afterward. She knew her life was in danger, so they faked her death and she had the baby soon after. (about 28 BCE is the best guess for his birth year) Her and baby Jesus went to Babylon (the one on the Nile, where present day Cairo is) with the help of the Magi. They didn't come back until Herod had died, when he was 30 years old, in 2 CE. He went by Simon Magus until just a year or so before the "passion" (in 21 CE). His father Josef helped him fake his death, and they went to Briton for him to recuperate. Josef and Marriam (1) stayed, but everyone else, including Josef's wife, Marriam (2) (the third wife of Herrod the Great) went back. Marriam (2) was the Biblical Mary Magdalene.
After he came back, he went by Paul, but continued to lead the movement. When the Jews did not follow him, he made war on their rich and all the Romans. He used all the tools of war common at the time. Fire, looting, rape and torture included. As Paul, he lived until the Romans cut his head off at age 84. Josef (known as the Old Man) died in 45 Ce, when he was 111. His grave is in Briton.
Seven of the disciples were his blood kin (half brothers and their sons), and two more were in-laws (a brother of Marriam (2), Josef's second wife, and his son). But they were all ultra rich from the leading political families. His half brother Nicodemus who helped Josef take him down off the cross, was one of the three richest men in Judea.
