Go easy on Lau...I have a book titled 'Hidden Stories Of The
Childhood Of Jesus' (Glenn Kimball, 2nd printing 1999). The author
has an extensive bibliography. I'm not expounding it as the truth,
but it does say that Joseph of Arimathea was also related to Mary,
a Senator and Noblis Decuro.
It's an interesting read that doesn't have to be taken seriously (I
could detect the author's unhappiness with people who object to the
extra-Biblical documents). It won't change perspectives about
Jesus, though there were miracles attributed to him in his
childhood.
