    I get the following -

    Europe West 38% (range 11-64%)
    Ireland 27% (range 10-45%)
    Great Britain 26% (0-57%) - the range is quite large
    Scandinavia 7% (0-23%)

    Here's my known ancestry (the one in the English Channel is actually my great great grandma who was born in Dover, her parents were Irish from Roscommon and Dublin counties) -

    If you want to understand why Ancestry get "British" so badly wrong, apart from technical shortcomings maybe, read the link below (a very basic understanding of British History is require) .
    Basically it goes something like this. Some of your British ancestors only arrived here (in Britain) about 1,500 years ago with the Anglo Saxons and Norse, therefore you aren't really British, you are German and Scandinavian. This is from a time when Countries didn't actually exist.
    Here is an amazing surprise, since we are an island, we all came here from somewhere else over the last several thousand years, therefore we aren't really British (so did everyone else, just about everywhere). We are all Africans really aren't we, on this logic?
    "It found that, despite the pervasive myth among some people of the ‘real’ Brit, the average UK resident is actually mixed ethnicity – 36.9% Anglo Saxon, 21.6% Celtic, and 19.9% Western (continental) European"
    British is basically Anglo Saxon, they say, the earlier inhabitants over the previous several thousand years seem to be mainly French and Spanish.
    The really bad news is if you are from America or somewhere else that has seen huge migration over the last few hundred years and you think you are an American or whatever, you ain't, you ain't even close. I'll leave it to you to decide whether this is just a lack of understanding. John

    on Ancestry .com that is. this company seems slanted towards the American audience......

    I'm fairly sure it's because Americans are often of mixed descent, and the GB category on Ancestry uses a fairly mixed reference population for its Great Britain category, the southeast English. It is interesting, and very confusing! The Irish and Western Scottish aside, Ancestry seems to be a very bad choice for people of British Isles descent a lot of the time, as we can see from the inconsistency in the results posted here
    Paper trail ancestry to the best of my knowledge:
    English 28.12%, German 18.75%, Scottish 17.96%, Irish (mostly lowland Scottish origin) 12.5%, French 8.2%, Eastern European 6.25%, Welsh 3.125%, Native American 1.95%, and Colonial American, 3.125%, which cannot be determined with complete certainty: there is Dutch (at least 1.36%) and some English. The rest could include Spanish, Norwegian, German, French, and Native American, but these percentages would be minuscule.

    All ancestry does, like all these ethnicity tests, is match you with the best "match".

    Myself for example, again:

    What do you think my actual ancestry happens to be?

    Livingdna Isles results break down as follows.
    Scotland/N. Ireland 51.8%
    English related. 27.7%
    Ireland. 14.7%.

    Due to circumstances beyond my control, I cannot confirm or refute these results. In my opinion, this is a concerted effort to 'Knock the Scot' out of me. The start of this effort was first encountered in earnest upon my arrival to the States. This has been recently verified by the US State Department issuing me an updated passport where place of birth has been changed from Scotland to the U.K. Now if I could only knock the Scot out of Ancestry's categories or are they in on it. Shouldn't have read the thread on neuroticism.

    John, I have read that about several of the DNA testing companies. Do not know for a fact though (I have no known or identified British ancestry myself). I am going to have to educate myself as well on the terms you just mentioned.

    What I'm saying is that if you pick a population that is mixed, then other people which are mixed are going to match with that population. We know that mixed people often get a lot of Great Britain, and that someone with all ancestry from Kent got 94% Great Britain, indicating that SE England is a place where lots of samples are from for the GB category. We also know that the southeast English are a genetically mixed population. So, mixed people end up matching with a mixed population; and to clarify that when I say mixed here I'm referring to mixed NW European people.
    Paper trail ancestry to the best of my knowledge:
    English 28.12%, German 18.75%, Scottish 17.96%, Irish (mostly lowland Scottish origin) 12.5%, French 8.2%, Eastern European 6.25%, Welsh 3.125%, Native American 1.95%, and Colonial American, 3.125%, which cannot be determined with complete certainty: there is Dutch (at least 1.36%) and some English.

    Mixed what though? They must share something to match up.

    I would have thought a company telling people whether or not they have British ancestry should at least understand how that ancestry is made up.
    The term "Briton" was first used widely by the Romans who invaded about 44 AD to describe the Celtic or Brythonic peoples who lived in what is now Scotland England and Wales, although these countries didn't exist that far back. Supposedly the Romans left little genetic impact on that population.
    The next big migration event was the Anglo Saxons and Vikings from about 410 AD. The Anglo Saxons did leave a significant genetic impact mainly in what is now England but even there it didn't entirely replace the DNA of the earlier population. Even in Eastern England which had the biggest impact, the Anglo Saxon DNA is estimated to be around one third at most, in other parts of England in the West it is considerable less.
    Then you had the invasion of the Normans in 1066 who apparently also left little genetic impact because of relatively small numbers.
    Britain is not England or "Angle Land". The pre-Anglo Saxon populations are most strongly represented in Scotland and Wales but also in England. This is a bit simplified, but just shows that it's much more complicated than presented.
    In my personal opinion the only existing DNA testing company that deals with Britain reasonable effectively is LivingDNA, at least they are realistic about what they can and can't tell you. John
