They are step brothers from Joseph being previously married and widowed, or they were kin possibly living in the same household.

Your chosen religion has ZERO data about these things you've just claimed.

OR???

“... zero data...”

must we shout?

The data is in the bible - these are sons of another Mary:

Matthew 27:55-56

Matthew 28:1

Mark 15:40

John 19:25

Also it is an unbroken Sacred Tradition that Mary remained unknown to man; “I do not know man”.

Adherence to Sacred Tradition (not human tradition) is required by the bible:

1 Corinthians 11:2
2 Thessalonians 2:15
2 Thessalonians 3:6

The bible itself is Tradition since its books included in the canon were for years orally passed on as Tradition before anything was written.

Very few early Christians were literate and even if they all could read, there was no paper available for copies. Multiple copies of books just did not exist in those times.

Sola scriptura is an error and not found in the bible.
