So the ossuary denies the virgin birth?
What kind of twisted logic did you use to get to that question. If James is the younger brother of Jesus it does not deny the virgin birth.
If Jesus is the son of Joseph, as you just said, then the Virgin Birth is a myth.
Now, about post 2061...

Matthew 13:55
55 "Isn't this the carpenter's son? Isn't his mother's name Mary, and aren't his brothers James, Joseph, Simon and Judas?
I didn't think I had to hold you hand by referencing Joseph as Jesus' earthly father.
I like your post #2061 I just don't like the only two conclusions you come to.
Now, there are two competing theories on the rest of the references.
#1. James the Lesser, son of Alphaeus, brother of Judas, brother of Joses is a relative of Jesus's earthly family and is in this way referred to as a "brother" of Jesus. He also has a mother named Mary, but not the same mother as Jesus.
#2. James, a son of Joseph and Mary, is a half-blood brother of Jesus. He is mentioned in a list of Jesus's "brothers" early in his ministry and then disappears from the narrative until sometime around Penetecost and the death of James the Greater.
The first Bishop of Jerusalem was James the brother of Jesus. This is the same James referenced in Matthew Matthew 13:55.
When Luke narrated the story of the Jerusalem council, it was "James" who made the final ruling on the situation with Gentile believers. (Acts 15:13-21) Although it was not made explicit in Acts who this James was, Paul's epistle to the Galatians provide the clarification. This is how James was introduced in Galatians:
Galatians 1:18
Then after three years I did go up to Jerusalem to visit Cephas and stayed with him fifteen days; but I did not see any other apostle except James, the Lord's brother.
