    If anyone would like a chuckle at some very strange results.

    I recently tested my maternal grandmother who is 50% French Canadian, 37.5% English and 12.5% Scottish on her paper trail. I just got her results below, and boy am I glad I’m not a novice at this because I’d definitely be reading into this if I were.

    England/Wales/North Western Europe: 91%
    Ireland and Scotland: 3%
    Norway: 3%
    France: 2%
    Cameroon, Congo, and Southern Bantu Peoples: 1%

    Edit: to be clear, it’s largely not that off base. The majority of her Scottish is from Shetland so the Norwegian checks out. The noise is just exceptionally noisy in her case.

    That's is the reason why you should not trust the DNA testing companies own results.

    I mean it doesn't seem that bad to me if we are looking at this from a different angle, Northwestern Europe: https://upload.wikimedia.org/wikiped...jection%29.svg

    A fair number of French settlers to what is now Canada came from areas of France that are green in the above map (some came from other parts like Gascony, Aunis, Angoumois, etc). We are also looking at rather Western European people (French, Scottish and English) who aren't that different genetically from each other.

    Exactly, ethnicity estimation should not be taken literally, ethnicity is not defined by DNA, there are many more factors at play there.

    Oh no, all in all it’s a good estimate. I fully expected a majority of her French to end up in the E/W/NWE category. And we’re from Shetland so the Norwegian percentage isn’t out of line either. It’s the erroneous 1% Cameroon that gave me a good laugh.

    Yes. You more you start to learn about autosomal DNA and population references + Of course History you will get the bigger picture. You can never get the exact results because it all depends on what population references you use.

    But for the beginners and regular people results like the one above can be really misleading.
    Whats up with the African 1 % by the way?

    Our paper trail and other areas of ancestry definitely don’t account for it. So it’s either an NPE or a hefty mistake on Ancestry’s part.

    Assuming it is a mistake on their part, results like this are absolutely misleading and despite the fact that I’m taking this fairly light heartedly, I did spend $100 for drastically false information.

    It is perhaps, noise? Maybe notify AncestryDNA?

    The last update seemed to weed out any of this really far fetched noise though, which is why I was so surprised it was there and so far off base, so I'm not sure if it should be attributed to NPE or noise, but either way I'm not sure Ancestry would really look into it. I can try though.

    Is the Congo, etc. new? Does it check out with Gedmatch?

    I tend to assume that something like SSA is usually correct, since it's hard to mistake it for something else in someone otherwise European (I got this idea from Razib Khan, on one of his podcasts). I get 0.2% Senegambian at 23andMe which I'd be inclined to dismiss as noise (not seen anywhere else), but for that and for the fact that I have a number of lines that disappear into 1700s colonial US south, so it's not impossible.
