LOGOZZO — My 4th great-grandfather was a Logozzo from Gioiosa Ionica.   To find the origin of the Logozzo male line, I had to find a Logozzo male cousin who was willing to test for me.   The Logozzo Y-DNA, which was inherited from my Logozzo ancestor virtually unchanged from 1000s of years ago, place him overall on branch R of the Human Male Family Tree.  All men today who are on Branch R of the Human Male Family tree are positive for the P-M45 mutation, and descend from this one man who originally carried this mutation.   This mutation happened about 20,000 years ago.    Since then, extra mutations have accumulated on the Y-chromosome, and broken up  Haplogroup R men into sub-branches.  (Haplogroup is just another name for “branch”).  The  specific Haplogroup designation of my Logozzo ancestor is  R1b1a2a1a1b (with terminal mutation P312+).   To see this specific sub-branch, click on the link Human Male Family Tree and go to Branch R.  Put your cursor over the letter  “R” and an arrow should pop up.  Click on that arrow.  That will take you to the sub-divisions of Branch R and then find the sub-branch with the P312 mutation.    Scientists think that this  more recent mutation of P312 occured recently in the Western Europe.  This may even be one of the indigenous male lines in Italy.    Today, you still find most Haplogroup R1b1a2a1a1b men in Western Europe  and in the surrounding areas.   My Logozzo ancestor came from this part of the world.   You can read more about Haplogroup R1b1a2a1a1b and and the associated P312 mutation here on Wikipedia’s website.
