Biblical evidence is that Joseph was the one that redeemed the body from the cross...only a relative could do that, and it actually shows Joseph became the guardian of Mary's family when Jesus' step-father died.

Historical evidence shows that Joseph of Arimathea was Mary's uncle. Do an Alta Vista search on "joseph arimathea uncle" and you'll find plenty.

Alta Vista? Tried a search of The Bible and nothing of the kind noted. It does say several things — he was a rich man, from Arimathea, a disciple of Christ... but nothing about him being Mary’s uncle.

None of the sources I'm seeing look very credible.
