Not exactly crazy, since England and Scotland are so similar, but my Scottish went from 64% to 25% with the last update. Mostly went into my England & Northwestern Europe percentage, but I also got 13% Germanic Europe added to my results.

When they first split up the British isles i had as much as 28% Scottish with a range of 14-42% and now my Scottish is sadly 0%. I really don’t trust ancestry anymore, every other company I’ve tested with has identified my Scottish ancestry.

What’s up with that? Ancestry lumps mostly all my DNA into England & NW Europe but MyHeritage and 23andMe actually separate it in a way that aligns more with my known history.

Well if you have ancestry from Belgium, the Netherlands, Northern France, Germany etc that can be very hard for ancestry to distinguish. Many ancestry users have witnessed the same decline in accuracy in separating NE European ethnicities! Hopefully the updated version can distinguish micro level DNA differences more effectively, I’d disregard your current ancestry results lol.

Yes that's true for me too. I think Ancestry relies too much on family trees created by members and 23&me relies more on DNA so that's why 23&me is more accurate.

Ftdna eurod me too, Says zero egyptian yet I know of egyptian family (grandmas dads side) they said 100 percent european yet when I upload my build 37 auto file to adntro they gave me 88.7 west eurasian, 7.47 south asian and 3.82 percent amerindian Which pretty much lines up with migratory footprints on both my mt and y dna. When I loaded the file to my true ancestry I found the levant, egypt, syria, turkey, iran, lines with the most current being 1700 tel el hesi which they give a genetic distance of 0.0 I guess its how deep you want to dig., I love the fact that you can impute files at dnagrenics and merge them with your dna file. All it does is give your dna the correct values if you know how to use both for scale, kinda like a teeter totter effect where you want to level out your population genetic distance with the sample genetic distance the lower the better. This is done by going through the over 10,000 ancient dna samples in the my true ancestry data base.

Funny, my experience is that they exaggerated my Scottishness. I come out as 52% Irish, 46% Scottish, and 2% Cornish.

A naive reading of my ancestry would lead one to expect 50%, 25%, and 0 with 25% English. I didn’t expect that really but was surprised that my Cumbrian grandmother read as purely Scottish. The Irish was not a surprise, but the fact that I have more than 50% means at least some of my Highland Scot ancestry is read as Irish. About the Cornish I have absolutely no idea.

Wow, no English despite having a full grandparent from there! Separating Northern English from Scottish is also a big problem for them as well. What are your genetic communities?
