    New Parental Phasing

    .
    Ancestry has started a new Beta feature.

    Dividing your match list into Parent 1 and Parent 2. And six other associated groupings. You do not need a tested Parent. SideView applied to your Match List.


    You can assign Maternal or Paternal to Parent 1 or 2. Click on the "By Parent Beta" to do this. For me, Parent 1 is Maternal. Which is interesting, because from the SideView, I could not tell (My parents had roughly similar ancestries).

    My Maternal and Paternal came out almost exactly equal. About 25,800 each.

    About 10% of my 55,000 matches are Unassigned. A lot of these have Common Ancestor hints and they may get phased at a later date. One is a 2nd 1r with over 100 cM so I find it hard to believe that they could not see him as Paternal.

    As far as I can tell the phasing seems pretty accurate. I have seen a few matches that are weird but at times my maternal and paternal sides co-existed in the same geographical areas, so I get some matches that seem to straddle both sides of my ancestry. I have seen one match (who triangulates paternal via DNAPainter but phases maternal) that I strongly disagree with, but overall very accurate.

    This phasing goes down to 8 cM. It is not applied to any archived matches from 6 to 8.

    there is a feedback form and I gave Ancestry high marks. I would like to see the phasing as a separate button, as it is currently clobbering the Groups button.

    Supposedly it WON'T be released until Tomorrow ( Thursday) but I got what seems to be parts of it 2 days ago.. I should explain that this is my up-to-now unknown Biological grandfather He was from Wales and the rest of the family was not..
    They gave me 6 new ancestors on my father's paternal line which extended it and several new matches on those 6.. actually a lot of new matches maybe 18 per ancestor . I believe they did this as my father's father is my only Welsh for me ( except for a few in early US(Delaware Welsh Tract.
    So I have 33% Welsh and my Sister has 40% The extra Delaware lines added maybe 10% to Dad..

    I'm interested to know who else got it early?

    Me, too!!!

    What I've seen so far is that the matches marked as maternal seem to be just that, and the matches marked as paternal also seem to be that. But of the matches marked as "unassigned", in fact I can assign most of these. In part that's because my parents don't seem to have any ancestral overlap in the last 300+ years.

    They do have some shared ancestries -- particularly British and German (including Swiss) -- but they're from completely different parts of the country: my father from Pennsylvania, with colonial-era German and British ancestry; and my mother from Biloxi, Mississippi, with British, Menorcan, Alsatian, French, Irish, Swiss, and Indigenous American ancestry.

    On the other hand, my mother's hometown is the location of a major U.S. Air Force training facility (it's how my parents met), so any of my father's relatives in PA who also went into the Air Force would have had a possibility of encountering relatives of my mother.
    Besides British-German-Catalan, ancestry includes smaller amounts of French, Irish, Swiss, Choctaw & another NA tribe, possibly Catawba. Avatar picture is: my father, his father, & his father's father; baby is my eldest brother.

    This one will be very cool and long-waited feature. I got it during midnight for a while; now it says error.
    My matches are mostly unassigned for now ( more than 1700)
    Parent one had 60 matches; Parent 2 - 147 matches. What is interesting is that they gave mutual communities which I don’t have yet; I’m posting a screenshot here of one example for Southwest Italy. Does anybody know if that community is new or it has been there? If it hasn’t ; then maybe new communities will be added?67C478E0-0DA3-4135-908B-BF4883C2C243.jpeg

    I tried it this morning. When I click on the button it gives an error.

    But when I look at matches it labels most and of those that indicate side, all I checked are
    correct, at least, they do match that side. A couple actually do match both sides.

    I can assign many "unassigned" ones.

    It found a very few ones that appear to in fact be both sides, which I have never noticed before

    I am skeptical about what AncestryDNA is trying to do. With current testing we can't tell which side an allele comes from. I doubt if the assumptions used in computation hold up.

    Dad - 3203 matches, common communities are NW Poland, Central and Northern Germany, Coastal NW Germany, and Wisconsin Settlers. Sounds about right, upper Midwest US cocktail of Polish, German and Scandinavian.

    Mom - 785 matches, common communities are Russians in Eastern and Central Europe, Central and Southern Finland, and Ukrainians in Eastern Europe. All Russian/Finn matches (grandpa), I have 0 French matches so this misses at least 25% of my papertrail.
    Known Ancestry: NW Russian 25%, Central French 25%, North German 25%, Scandinavian 12.5%, mixed Polish/German (Pomerania) 12.5%

    Itís interesting! I wish that there was a way to filter out American matches though as I think that, that can skew the surnames.

    Itís interesting though to see the difference in surnames on both sides, some of those surnames are in my ancestry, some not.





    A good attempt!
