The Da Vinci
Code: Bloodlines.
Aired on Tuesday, March 28 at
1:00am ET
Josh Bernstein searches for solid evidence behind
the controversial theory laid out in Dan Brown's book The Da Vinci Code.
Brown's theory claims that Jesus married Mary Magdalene and that she conceived a child.
It also suggests that the bloodline continues--unbroken--to this day.
Josh shows what's true and what's clearly make-believe in Dan Brown's bestseller.
From musty libraries to ancient churches,
Josh's unique quest leads him to seek the DNA evidence that might prove or
disprove one of the most sensational claims in modern history. Most remarkably,
he'll orchestrate the first ever DNA test on a Merovingian royal to find out
if the story of a divine bloodline stretching back to Jesus and Mary Magdalene
could possibly be true. TVPG

My conclusions on the FINDINGS OF HIS INVESTIGATION:
1. The DNA evidence indicated NO link to Middle Eastern DNA. The DNA was Western European.
2. The Merovingian blood line stopped hundreds of years ago because the last King had no children! Brown's geneolgy is fake.
3. French historic societies can find no historic record of a group called the Priory of Zion. They never exisited.
4.The book is total fiction with zero historic evidence.
