If you've not yet caught the sure-to-envelop-us-come-easter sensationalistic rah-rah about something folks are now calling "the Jesus tomb", you do need to check out Ben Witherington's post on the matter.
It is notable to check Witherington because he provides statistics on the relevant names that he received from Richard Bauckham. Bauckham is, from all I have read, one of the go-to guys in the realm of Palestinian names in the first century. That, tied with other stats Bauckham provides on the frequency of names found on ossuaries provides some good data by which to refute the sensationalistic claims made by the filmmakers of "The Jesus Tomb". So do check it out.
My take? I think the data on names, combined with the known sensationalism-mongering of the filmmakers (thoroughly documented and debunked by Chris Heard, check it out) combined with the fact that the tomb's original finders and excavators reached entirely opposite conclusions (the tomb was found in 1980, findings released in 1996) speaks volumes against what the filmmakers are proposing.
All of this sounds like you've stepped in on the middle of a conversation? Then you probably have. So check out Witherington's post for the background and some further information on how to handle the assertion when you hear it come easter.
