DNA test from ancestry.com?

I did the ancestry one. It was good at finding cousins (removed) that I didn't know about. The other surprise was finding a fair amount of DNA from Scandinavia. I was pretty sure it would come back almost all from Germany as both parents are from there ( my dad was born there and my mom's grandparents came from there on both sides). I had over 30% DNA from Scandinavia, IIRC.
