The various DNA sites keep recalculating. I have one Swedish great-grandmother, but now i seem to test out as Norwegian a little more than 50/50 vs Swedish. I guess I am just a Viking. That's OK -- but I don't understand. In the ballpark anyway
Just had my DNA tested and my wife did too with amazing results. I am, following statistical assessment of the past 5 generations, 38.% German and only 16.7% British. My wife, tested by a different firm was found to be 20% Irish Scottish and Welsh (?Celtic?).
I have therefore no Celtic DNA despite the fact that 50% of my ancestors came from Cornwall and a further 25% from Wales, and my wife has more Celtic DNA despite the fact that she is German with proven ancestry in Eastern Europe.
I am therefore more German than she and she more British than I....Marvelous what one can 'prove' from statistics, which reminds me....do you realise that statistically, the older you become the less chance you have of dying?

Another thought for the mix ….. and it is ONLY a thought!
Is it possible that the samples actually got mixed up 'at home'? Given two different companies were used it seems highly improbable that the results could come out as posted here so the logical conclusion would be that the tests were mislabeled prior to being sent for analysis.
The example might be that Tony and his wife went through the process at the same time. The two samples were then placed in their receptacles and put down on the table near each other whilst paperwork was completed. Once paperwork was completed each picked up a sample ignorant of the fact that they had selected the wrong one and hence the wrong samples went to the wrong company for processing.
As I said - just a logical scenario based on the information supplied.
Checking some of the 'matches' might give some further clues.
Samples were not mixed up. They were sent off at completely different times with at least two weeks separating them.
The problem is, I suspect, caused by confusion in the statistical interpretation of the results. I am said to be 38% German...don't forget Celts came from Middle Europe, Hallstadt being a good example. I neglected to say that my wife is reported to be more than 50% Balkan. She actually comes from an area of central Europe which politically was formerly in the Austro-Hungarian Empire...so were the Balkans.
I think modern categorisations confuse the issues. The tests have shown me to be 38% from central Europe (Celtic?) and my wife to have 20% from Scottish Irish and Welsh folk who remained in their Celtic homeland of Central Europe. But I still can't work out where the Tamil and Inca bits fit in and who was the Han Chinese interloper who invaded my family 5 generations back?
Ethnicity estimates are just that and vary by company. I wouldn't worry about it. My estimates on Ancestry are pretty accurate, My Heritage not so good. My matches on FTDNA are mostly Scandinavian. They factor in very small segments.
An interesting thing is that on my close mtDNA match list which is my totally Cornish line, I have Portuguese and Brazilian contemporaries. My haplogroup shows up as from the Basque region. So I guess my Iberian connection was good even though Ancestry eliminated it.
Work your matches; you know who you are. If those don't make sense, maybe you do have a test failure issue. Rare, but not impossible.

One thing I certainly am not is worrying about it. I find it fascinating and not a little comical.
I was fully expecting a huge wad of Celtic with a smattering of Iberian/Mediterranean and an unknown 'British' component. On paper I'm 75% Celtic and 25% British so wondered what my DNA would throw up. It's 38% German, 17% British 16% Italian 11% French 8% Slavic 7% Scandinavian and 2% Spanish. Further analysis shows I have 89% European DNA, 4% Mixed American (e.g Mexican Peruvian) and 4% South Asian 2% East Asian and 0.1% African.
What is fascinating is that 4 generations back they have identified a Southern Han Chinese gene and determined that this is 99% accurate. Don't know if this gene sneaked in from my Cornish family but it seems more likely that it came in from my maternal side and I have discovered that 4 generations back on my mother's line I have a g-grandfather who was illegitimate. The other maternal g-grandfather isn't known as I haven't been able to tract that line as yet. Who know...who knows?
The firm I used was CRI Genetics whilst my wife used My Heritage DNA

Tony, I had never heard of CRI Genetics. Usually these ethnicity estimates are based on the testing company's database including your matches trees and their origins. Even ethnicity results from Ancestry need to be taken with a pinch of salt.A small company like CRI even more so. CRI allows you to download your results. If you were then to upload them to GEDmatch for example, you may well get a completely different set of ethnicity results. I'd be curious to see if GEDmatch accepts CRI kits. I've never seen one on there before. You can also upload kits to My Heritage but you may have to pay to unlock their DNA tools.
