SANSOTTA — My 6th great-grandfather was a Sansotta from Gioiosa Ionica.   To find the origin of the Sansotta male line, I had to find a Sansotta male cousin who was willing to test for me.   The Sansotta Y-DNA, which was inherited from my Sansotta ancestor virtually unchanged from 1000s of years ago, place him overall on branch I of the Human Male Family Tree.  All men today who are on Branch  I of the Human Male Family tree are positive for the M 170 mutation, and descend from this one man who originally carried this mutation.   This mutation happened about 22,000 years ago.    Since then, extra mutations have accumulated on the Y-chromosome, and broken up  Haplogroup I men into sub-branches.  (Haplogroup is just another name for “branch”).  The  specific Haplogroup designation of my Sansotta ancestor is  I1 (with terminal mutation P253+).   To see this specific sub-branch, click on the link Human Male Family Tree and go to Branch I.  Put your cursor over the letter  “I” and an arrow should pop up.  Click on that arrow.  That will take you to the sub-divisions of Branch I and then find the sub-branch with the P253 mutation.    Scientists think that this  more recent mutation of P253 occured recently in the Northern Europe or Scandanavia.  Today, you still find most Haplogroup I1 men in Northern Europe  and in the surrounding areas.   My Sansotta ancestor came from this part of the world.   You can read more about Haplogroup I1 and and the associated P253 mutation here on Wikipedia’s website.
