If he had brothers they obviously did nothing of note
Jesus brother James was pretty noteworthy.
Ref New Testament book of James.
Mat 13;
54He came to His hometown and began teaching them in their synagogue, so that they were astonished, and said, "Where did this man get this wisdom and these miraculous powers? 55"Is not this the carpenter's son? Is not His mother called Mary, and His brothers, James and Joseph and Simon and Judas? 56"And His sisters, are they not all with us? Where then did this man get all these things?"
They got more column inches as authors in the New Testament than several of the twelve disciples, eh?
kind of a hard act to follow
James wrote a book of the new testament, I’d say that’s noteworthy.
