Ancestry test , how accurate?? .my Result shocking

They aren't accurate. I read about identical twins having completely different results.

accuracy is very low. so best to bin the results & ignore it.

The accuracy is great for "connections". So if it linked you to someone as Second Cousins, then you are probably related to a similar degree.
However the ethnic matching can be very hit and miss. It just depends on their base samples (I think volunteers whose grandparents were all born in the target area).

If it is a small portion of DNA it can easily be explained as happening hundreds of years back, maybe before the family was traced back to since there has been massive amounts of human migration.

Even if someone has done the dirty a few generations ago why does it matter?

I doubt if anyone has 100% British DNA.

Celts came from eastern Europe didn't they?
(several thousand years ago!)

They are very innacurate. It’s possiblr it’s picked up one marker and based the result on that.

About 120 years ago, there was a massive hoo-ha in the press about Jewish migrants from Eastern Europe and Germany coming over stealing our jobs, pushing wages down, increasing the cost of housing, not integrating .

Many completely Anglicised their names due to the racism they experienced from some quarters, some did so following the declaration of war in 1914 and, as their children were white (and were very often blonde haired and blue eyed, like my GM) and grew up here, they were not seen or known to be anything other than English, even by their spouses and children.

We've always had migration. It's a falsehood perpetuated by certain groups that it's a new phenomenon. The type of people that proudly claim to be 100% English, usually.

When you say she has traced her father's side of the tree back to the 1600's - does she meal all of them? Both the male and female lines all the way back?

her DNA is almost 100% British but her DNA is showing up as eastern European

So was it British or Eastern European? Somehow everyone else understood but I live in confusion.

Is she coming up as relative to known cousins on both her dad's & mom's side?

I agree with MitziK that it is mostly likely to be from when East European Jews were persecuted in the nineteenth century and many came west.

I think it would be vanishingly unlikely that you could go all the way back to the 1600s and not have someone do the dirty. Likely several times over in different branches.

I have a half remembered fact that someone ( who doesn’t have a menopause brain) will no doubt be able to clarify. Isn’t it that your dna is just being matched up against all the other people that have been tested, or something..,,

That was helpful, not

Apparently 1/10 children don't belong to the men who think they're the father

My understanding is that these particular DNA test shows where other people who share your DNA (i.e. close relatives - but not sure how close) live now. In other words, people who have also taken Ancestry.com tests.
Absolutely nothing to do with where your ancestors DNA comes from.

It's more to do with where people sharing your DNA now live, rather than where your ancestors came from.
And ignore the Ancestry.com bit - complete typo fuck up

Nothing to constructive to add to the thread other than the advert at the bottom was for ancestry dna or some such website

@YeOldeTrout

I think she means the dna is almost totally British but with a small amount of Eastern European.

That’s what I don’t quite understand about admixtures, is it based on an idea that at some point in history there was such a thing as a 100% East Asian, for example, race of people that present day people are measured against to see what percentage they share? It seems not v likely given what we know of human behaviour.

Having said that it’s still a helpful tool when you don’t know where to start looking.
