I noticed that the ethnicity estimates have been altered, not sure when, and I appear to have acquired 3% of Welsh, where from I can't imagine.

And I know we don't have to take it too seriously!
However, they have also divided the DNA between parents, which has left me really baffled. The bit of Scottish has come from one parent, my father, which I understand, but the similar amount of Irish and the little bit of Welsh are from the other parent, and that makes no sense to me at all. There is a known bit of Irish in father's ancestry, and a missing line through illegitimacy, but mother is solidly Kent on one side and Essex/Suffolk on the other.
Any ideas on this please?
