AncestryDNA have done another of their regular revisions of my sample. I am no 98% Irish, 2% Scottish, and <1% Sardinian. I have been 2% Scottish before as I remember.
I will put a label DNA on this post, then gradually retrospectively apply it to earlier ones to help me get a better handle on the trends and changes. I seem to remember that initially I was only 79% Irish for example.
