. . . in the 
Gospel of Mark the only mention by names of Jesus' family -- with an important exception -- is this well-known passage:
	
		
			
				Mark 6:3-4 said:
			
		
	
	
		
		
			Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him But Jesus said unto them, A prophet is not without honour, but in his own country, and among his own kin, and in his own house.
		
		
	 
That's it!!  Father Joseph is mentioned ZERO times in the entire Gospel.  Brother James -- who became a top pillar of the Church before the Gospels were written -- is mentioned ONLY here in all the Gospels.  (Matthew and Luke offer the same list of brothers; Matthew replaces "the carpenter" with "the carpenter's son," still not naming Jesus' father except in the Nativity myth of chapters 1-2.)
I wrote that there is an important exception; a place where 
Mark does repeat his mention of Mary and two of Jesus' brothers.
	
		
			
				Mark 15-16 said:
			
		
	
	
		
		
			[15:40] There were also women looking on from a distance. Among them were Mary Magdalene, Mary the mother of the younger James and of Joses, and Salome. These women had followed him when he was in Galilee and ministered to him ...
. . .
[15:47] Mary Magdalene and Mary the mother of Joses [Joseph] saw where Jesus' body was laid.
. . .
[16:1] And when the Sabbath passed, Mary Magdalene, and Mary the mother of James, and Salome, bought spices, so that they might come and anoint Him.
		
		
	 
The "other Mary" is the mother of James and Joses, and therefore also the mother of their older brother Jesus!  But does it seem odd not to just call her "Jesus' mother"?  For some reason the author of 
Mark is reluctant to say this out loud!  Why?  (
Matthew and 
Luke have the same reticence, with the former changing two instances of that Mary to just "the other Mary." 
John refers to Jesus' mother, e.g. in his famous last words, but mentions her 
by name . . . ZERO times.
This reluctance to identify Mary as Jesus' mother strikes me as peculiar -- 
and should seem peculiar whether you treat the Gospels as fact or fiction.
Does the reluctance to name Mary, Joseph and Jesus' brother James seem peculiar?)  This James is called "the First Bishop of Jerusalem", and was assassinated in the 60's AD, BEFORE the alleged writings of the Gospels.
