Ancestry Tests - Lods - 11-16-2021
Ancestry DNA test (or others)…. Anyone done one. I had some interesting results from mine done a few years ago. Every now and then they update it as more tests are done and more information comes in.
Currently mine is…
40% Ireland
39% England and North Western Europe
9% Scotland
6% Wales
4% European Jewish
2% Swedish and Danish
Through the test I’ve made contact with the son of my grandfather (my uncle). He was born after my grandparents separated… and my own father had no idea of his existence. They never met but lived for 30 years in adjoining suburbs.
I was not surprised with most of the results but the European Jewish is an interesting factor.
Given the spread of the Jewish people through Europe, and specifically Germany, through history... I wonder how a certain Austrian painter and his circle of friends would have gone on an Ancestry DNA test. I suspect we may have had a very different history if they’d been available in the 1930s.

Did you go through a particular site for your ancestry test?

Either Nature or New Scientist did a analysis and critique of the commercial ancestry services a couple of years back, based on those findings it would pay to be very sceptical of any "individual" result.
The problem seems to be that the science methodology used by the commercial ventures is a corruption of scientific techniques designed to look at society wide averages using statistical analysis, and is not designed to be accurate for specific cases.
This was exposed by taking the same DNA sample and having it tested in more than one geographic location within each organisation, the resulting reports varied in conjunction with each locations different genetic diversity. It was explained as being due to the broad assumptions each testing location must make based on census type data. They make the analysis by starting with an assumption about the person being tested.
It is not just big geographic moves that cause this problem, like from Sweden to Africa. They even found the tests from some organisations varied widely with relatively small geographic shifts, for example from England to Italy changed the reported result.
That doesn't mean it is not worthwhile or fulfilling as a hobby project, but the results are legally next to worthless.

My wife did them through ancestry.com, found cousins she didn't know about and not distant ones either. Some uncles having kids out of wedlock etc..it's a small world when dna testing is involved.
Problem is the further you delve the more money it costs to construct your family tree.
We get the updates as the technology improves and my wife loves the new family contacts...

At 2% difference / variation levels, nearly everybody on earth is matched via some ancient measures. We may all be 2% Denisovan.

Hopefully, @DJC can comment for us in plain language.

I used Ancestry DNA
The geographic sites match up pretty well to our own known family history.
The most impressive feature is that we've had about a dozen of our family take the tests and they've nailed the relationships.
The long lost uncle (no one knew about) showed up as third in my relationships behind my own daughter and my aunt (Mother's sister) and ahead of my first cousins. His daughters show up as cousins.
You can perhaps question the ethnicity factor but the relationship factor seems to be quite accurate.

Also for my own interest, how did you get into it, was it from talking to a relative?

You will find a lot of people are equally interested in proving who is related to who than the ethnicity side of things.

Just on location...
Ancestry identifies my wife as having a strong South Australian element to her family and mine shows up as mostly Victorian that's accurate.
They pinpoint the specific area of Ireland where our relatives originated from (Galway Mayo)
On the other hand they do provide a rather broad range e.g My 39% England Northern Europe is actually a range of 30%-51%
Accuracy of ethnicity may be dependent to some extent on the volume of samples in the database.
The more folks that take the test the more dependable the database.
But as LP suggests there may be many other factors involved, so if anyone can enlighten us?

No questionaire...just a saliva sample.
My wife took the test first. She has quite an interest in family history. I thought her results were interesting (although they don't vary a lot from mine). She has a bit more Scottish and some Baltic state showing up in hers.
