You wrote that you “feel like I’ve been given someone else’s test results!” since you got the results:
“Ancestry Autosomal DNA test supposedly I am 70% Scandinavian, 23% Eastern European ( which I expected ), 6% Finnish, 1% Unknown.” and you have a documented British, German, Balto-Polish background.

Well, I do not know about the accuracy of the test, but to me your results could actually make good sense (perhaps):
The Baltic people have for thousands of years lived along side with the Finns so the Finnish admixture is no surprise. The high percentage Scandinavian genes may not be that strange since you describe your British forefathers originate from Yorkshire which is a area with very concentrated viking settlement. Viking from all areas of Scandinavia (even from the Eastern side o Scandinavia and in Stockholm there are rune-stones describing how explorers earned fortunes in England plus plenty of artifacts). The name York, furthermore, comes from the Scandinavian Jorevik and there is a huge museum in Central York where you can study the city’s Scandinavian heritage. Most Scandinavians outside the city settled down in areas with poorer agricultural conditions which the former Celtic and Germanic (i.e. older immigrant periods from Dutch-German-Scandinavian areas) immigrants had left uncultivated which can be studied in the village names of e.g. Yorkshire.

Also during the age of tribal movements in Europe (circus 200-500 AD), several tribes moved from Scandinavia into today’s England, Finland, France (the Normans in Normandy), Germany, Ireland, Poland, Russia and Scotland among others. Furthermore the Baltic states have for many hundred years been under German and Scandinavian control which also added to admixtures.

Considerable Viking settlements occurred also in the Irish cities of Dublin and Belfast (a part of the UK).

So, perhaps the 70% Scandinavian result can be explained and plausible to some extend?

Later on during the 13-15th century (German), 16th century (Scottish-Dutch), 17th century (French-Belgian) immigrants came to different parts of Scandinavia making up a part of the present day population.

So, I guess the gene map is more or less a patchwork all over the world.

My results linked to someone within 3 miles of the town I had identified as my fathers home town, so no question of paternity. How is it then that my mothers putative ancestry is not British while mine is? This would seem to contradict the speculation about invaders and suggests an alternate possibility, that the identification is inaccurate.

60% British Isles
26% Scandinavian
9% Persian, etc.
5% uncertain.

Autosomal test
75% British Isles
25% Scandinvian
9% Persian,Turkish.Caucasus
5% uncertain.

I have not found any exact matches, yet, but most of the surname matches have been to people with the same Acadian surnames – Boudrot, Landry, etc. that are not reflected at all in the DNA test. I am seriously considering doing another test with FTDNA. I had my brother do a Y-DNA test with FTDNA and got some unexpected results, but the Irish and Acadian ancestry is on my mother’s side. Her mother was first generation Irish and her father was born in Nova Scotia. I can see where the Irish might be Scandinavian, and I can see where the French might have some Middle Eastern, but the total lack of Central Europe is a bit surprising.

What has occurred is that the base data has been skewed. It get’s worse when base data participants “self identify.” This is particularly problematic with Jewish groups and as we can see it has spread.

In regards to Askenazi Jewish groups a recent paper pointed out that nearly 40% of all Italians share a connection to Ask. Jews. Meaning that Ask.Jews came out of Italy at some point. “The origin of Eastern European Jews revealed by autosomal, sex chromosomal and mtDNA polymorphisms” Avshalom Zoossmann-Diskin,

Since most Mexicans probably have some Spanish ancestry, and Spainards are autosomally connected to Italians next, and Italians are next autsomally connected to A.J. then I think the genetic sites are jumping to the next conclusion that some Mexicans are AJ as well (since AJ is connected to Sephardic)…..I’m not saying that withing reason say 3%-6-10% of Southern Spaniards and Mexicans have some Jewish ancestry, but the reporting I keep seeing is out of bounds.

Ancestry claims that the test is “more recent targeting of family history of a 100 or a few 1,000 years as compared to the Y & Mt DNA test which is 10,000-50,000 yrs.”
They also say that, “If you have German or Brit ancestors your genetic ethnicity may be PARTLY Scandinavian”.

Soooo – My tree – Paternal Grandfather 100% Irish, Paternal grandmother 50% German & 50% English. Each of the G Grandparents being 100% German/English.
My maternal side is Polish/Lithuanian 50/50 or there about.

I STILL have relatives living in the town mine come from (mid Germany) – which was settled in 900 AD. My English relatives go back to the middle ages in Yorkshire…
NONE of which shows up in my DNA as British Isles or Central Europe (?!) Nothing? Not even 5%?? How is this possible? I feel like I’ve been given someone else’s test results!
