It's pretty obvious that Parent 1 (Wales 26%) is my mother's father and Parent 2 (Scotland 27%) is my mother's mother. It is interesting that Parent 2 is the source of the 4% Norway- I seem to recall someone saying that side had blonde hair and blue eyes (I never knew them) and it makes me wonder if my illegitimate 2nd great grandfather's unknown father was responsible for that- probably a mariner.
Does this mean they'll eventually offer a guess about whether a match is on mother's or father's side based on this? It would be interesting to know which matches share the 4% Norwegian, for example...
