Well do you believe in the accidental death scenario, or the usual alternative of Madeleine walking out of the apartment , and disappearing ?
People can believe what they wish.
Meanwhile we have the second comers, where the originator believes Madeleine is the second coming, and firmly believes, he and Madeleine are descended from JC. 
Well it takes all sorts, doesn't it Alfred ? 
Well we already have someone on this forum whose family believe they are descended from Jesus.
Lyall is a St Clare [Sinclair] and there is fairly wide belief that this family are descended from Jesus. The Sinclairs are also the people of the mysterious Rosslyn Chapel just seven miles south of Edinburgh [Dan Brown and all that]
It is widely thought that Jesus did NOT die on the cross but was rescued by Mary Magdelene and some friends. It is thought that he was taken initially to Cyprus, then on to the South of France. It is thought that he married Mary and together they produced a family, of which the St Clares are direct issue.
Look it up yourselves on the internet , if you dont believe me.
Despite what The Catholic Church claims, Jesus was a Jew. He came from what is now Israel and the people who lived in Israel, Judea, Ammon etc were called
Caananites. It was a general term covering all 12 tribes of Dan in that region at Jesuses time..
Gerry Mc
Cann is also almost certainly of a Jewish bloodline, originating in Israel or one of the 12 Caananite sub-regions
PLEASE NOTE THAT SPELLINGS CHANGE THRU THE CENTURIES.
Mc / Mac means * OF *,
So Mc
cann means " OF
Cann "
Kates family name, Healey, is definitely Jewish. I found that on a Jewish names website.
With both parents bloodlines being Jewish and it seems Gerrys (and possibly Kates) originatiing at Old Testament Biblical times from Caanan, [Palestine] there is a definite possibilty that Madeleine, (Beth!), could be descended from Jesus.
All the research has been done by me, as a keen ameteur ... and it is possible that I have reached incorrect conclusions.
BUT so much is now falling into place, that I think I am right.
Madeleine has Jewish blood and
could be descended from Jesus.
Some people may be able to trace back via the Clare bloodline, or some other Jewish [ ?Clare, Mccann or Healey? ] bloodline. I am too tired to do that.
