Do an Alta Vista search on "joseph arimathea uncle" and you'll find plenty.
None of the sources I'm seeing look very credible.
Nothing looks credible if you don't want to open your ears and eyes. It's the same thing with liberals and the bible...I used to think they were too stupid to realize the bible is true. Now I know that they don't want it to be true...they refuse to believe the bible is credible.
