    My mum's is funny, as far as I know everyone was from UK, certainly for many generations. To preface that, both Living DNA and Ancestry give her very substantial amounts of eastern English ancestry, which is dead on from paper trail. (ie: East Anglia, SE England genetic communities) However, I can't make sense of the 23andMe update, but possibly the rich Anglo-Saxon ancestry is getting mixed up with Germany.

    British and Irish: 48.5% (United Kingdom : Highly likely, Ireland: Possible)
    French and German : 28.1% (Germany: Possible match)
    Scandinavian: 4.1%
    Broadly NW European: 17.3%
    Broadly S European: 0.4%
    Broadly European: 0.6%

    SSA:
    Congolese: 0.9%

    East Asian:
    Manchurian and Mongolian: 0.1%

    I'm really not sure on the last 2. Typically the same West African segment appears in 3 generations of our genomes in Admixture calculators, but now it's more specific - Congolese. I really don't know how, but perhaps there was a Belgian colonist somewhere who brought a woman. The Mongolian is even more puzzling, but one of the old iterations of AC showed her as 1.7% East Asian. I considered it a false positive at the time, but I really don't know.

    The SSA and EA aside that looks a lot like my dad's result. Looking at your result I'm more certain that English ancestry is being placed in the French and German category in large amounts.
    Paper trail ancestry to the best of my knowledge:
    English (possibly containing some Welsh ancestry) 31.25%, Eastern European and Eastern German (Galicia, Poland) 25%, Scottish 17.96%, Scotch-Irish 12.5%, French 8.2%, Native American 1.95%, and Colonial American, 3.125%, which cannot be determined with complete certainty: there is Dutch (at least 1.36%) and some English. The rest could include Spanish, Norwegian, German, and French, but these percentages would be minuscule.

    The one "glitchy" thing I'm seeing is that Ancestry Composition is showing 1.2% Spanish & Portuguese and 1.0% Italian for my daughter -- both from me. The trouble is, 23andMe now only shows 0.8% Spanish & Portuguese for me, and no Italian -- although before the update, I think they did show about 1% Italian for me.

    Comparing our paintings, I can see that's my daughter's Italian is all in the form of a single segment on chromosome 1. I am also reminded why a certain decision of 23andMe's aggravates the daylights out of me. It's this: 23andMe clearly uses terms like "broadly Southern European" to mean regions identified as being southern European, but not more specifically assignable. In other words, it isn't the same thing as "all Southern European". It certainly isn't the same thing as "everything".

    So why did 23andMe make the decision not to give such regions their own separate highlighting? This would make it easier to look at an Ancestry Painting and say, ah, these segments are broadly X, but that's all they can tell. As it is, there's no highlighting for these "subregions", I suppose just because they aren't specific. But they certainly are more specific than "everything"! It would certainly be useful for me if I could, say, compare the same part of my chromosome 3 to my daughter's and say, "Oh, she has Spanish & Portuguese here, but I have broadly Southern European." Instead, I can see her highlighting clearly, but I have to try to decipher different intensities of blue for me!

    (Yes, I know; I can download the csv files from the "Scientific Details" page for each of us. But just allowing highlighting of the "broadly" subcategories would help.)

    EDIT:

    Okay, so comparing the .csv files -- a very useful feature, by the way -- I can see that Ancestry Composition says I have "broadly Southern European" on my maternal copy of chromosome 3 from 4,261,304-121,660,664. Ancestry Composition says my daughter has "Italian" on her paternal copy of the same chromosome from 63,411-56,475,423, and "broadly Southern European" from 56,475,423-64,160,129.

    So at least I have "broadly Southern European" at the location -- rather than something totally different. So the question would be, why would Ancestry Composition be more specific for my daughter than for me in this case?

    The answer could be that I have phasing against only one parent, where she has phasing against both parents. In theory, her phasing should be more accurate -- because there should be fewer SNPs that can't be resolved. (This would be where both parent and child are heterozygous, so you can't know which SNP was from which parent.)

    Still, 23andMe offers a heck of a lot more functionality that Ancestry. (Ancestry doesn't even have a chromosome browser. And for their ancestry analysis, you only get percentages -- not a display of where each ancestry is believed to be located in the genome. That makes it possible to compare to family members, and even associate ancestries with actual ancestors.) I just wish 23andMe's customer base were as large.

    Besides British-German-Catalan, ancestry includes smaller amounts of French, Irish, Swiss, Choctaw & possibly Catawba. Avatar picture is: my father, his father, & his father's father; baby is my eldest brother.

    This new estimate actually brought the composition the closest yet to my known paper trail

    French & German 21%
    British & Irish 20.1
    Scandinavian 17.8
    Ashkenazi 12.3
    Eastern Eur 3.6
    (Poland)
    Broadly NW Eur 23.3
    Broadly Eur 1.6

    The German had never matched up--my paternal grandmother was first generation American from a German family, this now reflects that. I found it interesting that the Eastern European specified Poland, as the father of my Jewish great grandfather was born in Poland. The slightly depressing bit of information came where they now gave the occurrence of my mtDNA on 23&me--1 in 6,700!

    @geebee I saw that you had origins of the Balearic Islands, I myself have a great great Spanish father certainly of the Balearic Islands, before the update 23and gave me 7.1 Iberian, now I have 5.4, I think I should have more.
    some test gives me the right amount like 24genetics or Lukaz k36.
    Maybe the Balearic Islands are less attributing Iberian than other region?
    sorry for lousy English

    I'm on the V4 chip and received (was able to view) this update yesterday. My Ancestry Composition version number had been V2.0 as of Oct 11, 2018 then changed then to V3.0 like yours. (change date actually is listed as January 06, 2019 - my birthday!) I believe people tested on the V5 genotyping chip have been at AC V3.0 since their AC update months ago.

    Similar to yours, my "Recent ancestor locations last computed on December 14, 2018"

    Only minor changes for me - basically, they upped my more specific regions and lowered the Broadly categories. Lost Norway as a sub-region but gained Germany. Also noticed they dropped that 0.1% in North Africa.

    I believe you are correct, I have AC V3.0 and my update is dated from December 20th. However the change from Iberian to the obviously-backwards-named Spanish & Portuguese only happened "now", but the results themselves are unchanged since I first got the results (V5) a few months ago

    Mine (V4) changed a bit in the update but my mother’s (V5) did not.


    British & Irish 62.9% (down 10%)
    French & German 15% (Up 10%, no locations)
    Scandinavian 0.9% (Came back, I was originally 1% then lost it)
    I lost my 0.2% Iberian
    My 0.8% West African has been reassigned as 0.7%
    0.6% Congolese
    0.1% Sierra Leon, Liberia

    I’m not really sure what to make of the 10% gain in French and German but with no Ancestral locations. I would think of undefined Continental ancestry would have been lumped into one of the broad categories. It’s not too bad though, all of my known ancestry comes from Britain, except for a few Norman lines way on back.

    My mother shares the 0.6% Congolese on the same spot on the same chromosome as me, and I have a 0.1% Ghana, Liberia, and Sierra Leon on my 12th chromosome I must’ve got from my father, they divided up, instead of just West African.
