BELCASTRO — The Belcastro family is from Martone.  The Belcastro Y-DNA, which was inherited from the original Belcastro ancestor 1000s of years ago, place him overall on branch G of the Human Male Family Tree.  All men today who are on Branch G of the Human Male Family tree are positive for the M201 mutation, and descend from this one man who originally carried this mutation.  This mutation happened about 14,000 years ago in the Caucausus or the Middle East.  Since then, extra mutations have accumulated on the Y-chromosome, and broken up  Haplogroup G men into sub-branches.  (Haplogroup is just another name for “branch”).  The Belcastro specific Haplogroup designation is G2a3a1 (with terminal mutation L14+).   To see this specific sub-branch, click on the link Human Male Family Tree and go to Branch G.  Put your cursor over the letter  “G” and an arrow should pop up.  Click on that arrow.  That will take you to the sub-divisions of Branch G and then find the sub-branch with the L14 mutation.    Scientists think that this  more recent mutation of L14 occured less than 4000 years ago in Turkey or the Middle East.    Today, you still find most Haplogroup G2a3a1 men in Turkey, Greece, and the Middle East, and in the surrounding areas.   The Belcastro ancestor came from this part of the world.   You can read more about Haplogroup G2a3a and the associated M406 mutation here on Wikipedia’s website.
