I've been having a look around at my family history and constructing a family tree. I knew nothing about my mum's side. Turns out I'm partly Norwegian (5% perhaps).
They arrived in the 1870's. They came straight from Norway. https://www.geni.com/projects/New-Zealand-Settler-Ships-H%25C3%25B8vding-1872/12817
My dad's side is interesting as well. Some inbreeding. Racism. And a link to the British aristocracy going back 1,000 years.
So far my composure is 15% Maori, 10% Norwegian and 75% English/Irish (they migrated from Ireland in the 1600's) if I were to guess.
