The largest proportion of my DNA is Irish, Scottish, Welsh. I've researched all the branches of my family going back hundreds of years and there is no Scottish or Welsh. I have one great grandfather and ggmother who are Irish. On my mum's side, the heritage is primarily Cornish. Is this officially Irish DNA?
I have wondered this. As I have a surprisingly high % of Scottish/Irish. But if it included Cornish this would make a lot more sense (a lot of my Ancestry is originally Cornish and lots of marrying back to Cornwall after they left).
