    What is the Scottish component composed of?

    I have known about distant Scottish ancestry in my heritage, so I do not question that I have it. What I question is the amount.

    On AncestryDNA I am allocated 37%, which isnít out of question. However, a lot of other sites mark me as 90% Irish.

    I am now feeling confused about what my heritage actually is. Further to this, the recent FTDNA update has brought about additional questions.

    - Some of my matches have 100% Irish in Ancestry but 20% GB in FTDNA?? What? How can this be the case?
    - Is the Scottish component a western Scottish component? I ask because I note that most of my pure Ulster Irish matches are recording a background 10-20% Scottish in the AncestryDNA test. Can one assume Gallowglass is present in most people here?

    I am viewing the Irish components as a Celtic component for Scotland and Ireland. I donít believe I am 100% Irish. So perhaps the Scottish component is influenced by Irish migrations??

    I am just questioning what my true ethnic make up is, as my results are so conflicting.

    My mother is mostly English on her mother's side (Essex/Suffolk boarder & Kent who immigrated to Canada mid- to late-1800s), and Irish & Scottish on her father's side (Argyll in Scotland, and Sligo & Cavan & Down in Ireland, with immigration happening early 1800s).

    She gets 44% England & Northwest Europe, and 44% Scotland.

    Now I'm pretty sure the ancestors from Down came from Scotland a few generations earlier, but otherwise that's the mix. Hope this information could be useful to you!

    Edit 1: also all her Irish ancestors were Protestant Methodists.

    My wife’s maiden name is Scottish, though her ancestors had been in the London area for years. She now has 47% Scotland.

    I was assigned 4% with no ties to GB, Scotland or Ireland. While minor, I have seen some other German members with higher assigned amounts. There was an explanation for the German assignment attributed to a migration back in the 1700s. Seems like there is a more recent Scotland/German connection. The map also encompasses NW France, so there is a possibility there too.

    I'm thinking some Irish Protestant may be misread as Scottish due to minor amounts of English ancestry, so the Scottish reference pop could be largely Lowland.

    The common pattern in all your threads seems to be that you really want to identify a large part of Scottish DNA in your ancestral make-up. Surely you have some but from what I've seen of your results most of the time you're presented as overwhelmingly Irish. The smaller the Scottish part of your heritage is the more difficult it will be to separate from the Irish. I think your goal cannot be accomplished. Maybe if whole genome sequencing really picks up in the future you could potentially use that to compare and find whatever you're after

    I think it will be hard to detect differences without a lot more testers with accurate origins information. This is only complicated by constant movements back and forth across the Irish Sea over the ages. I think parts of Northern Ireland are only 13 miles from Scotland.

    You can go back to the Irish Genome study by Lara Cassidy. They have what they call the Irish Genome as being establishing 4000 years ago when the Bell Beakers came in. They say that was a major change in the genetic makeup of the Irish. They also show that today's Irish, Scottish and Welsh have changed little since then. In other words, they are the same people.

    For detailed refinement is needed. My guess is there are a couple of north Irish types that are more closely related to western Scottish types than they are to southwest Irish types. Need more numbers.

    Thatís mostly what my question is. I noticed that some of my results are highly Irish whilst others are a mix of Irish and Scottish.

    That combined with the Scottish being present in Ulster Irish samples has me wondering what the Scottish sample is composed of ethnically.

    Here is an example of what I was saying above. These are all people with near 100% Ulster Irish Dna.

    Common trends:
    - 10-20% Scottish, some Welsh.
    - All have the Northern Ireland and SW Scotland Genetic Community.

    Why is the NI and SW Scotland GC basically in all Northern Irish results despite ancestral background?

    This is probably more common than we think, I'm not sure of the stat, but we do know that a certain amount of native Irish converted to Protestantism in Northern Ireland especially, this can be reflected in ethnicity estimates. Secondly, separating Scottish from Irish can be quite difficult once we consider that both nations have rather connected histories throughout the centuries that muddies the waters.

    My cousins in Northern Ireland who have seemingly only Protestant Ulster roots are often estimated to be almost entirely Irish.
