Sounds awfully familiar: I saw a documentary a few months ago about an ossuary which surfaced in Israel which was alleged to contain the bones of Jesus' brother "James". After the initial excitement several experts eventually agreed that the carved text wasn't consistent with known text of the time and perhaps more damningly one of the people in its line of provenance was shown to have been invloved in fraud and antiquarian forgery before.

Article from 2008 during the trial:

I'm not sure what the eventual outcome was.
The name's Christ, Jimmy Christ.
