Well you know, Persephone, Teutons is the entire group encompassing Saxons and Vikings among other things, so I understand what you mean, but I'm just demonstrating all the different people who are considered "Germanic" et cetera.
One cool thing that I learned, how Nazis would try to pursue the true Aryan race and kill everyone else, and they killed gypsies too, from Romania and Hungary and that area, but it turns out that the gypsy-folk from southeastern/central Europe are the original, pure Aryan race. I just thought it was an interesting bit of info.
And Celts are different looking than the rest of the Northern Europeans because there were tribes living in Ireland and Britain as well, and, like the British colonists in Jamestown, Virginia in the 1600's, they were just assimilated into the native culture. The same goes with Italian people; the Germanic/Gothic tribes living there were combined with Phoenician, Hebrew, Greek, and North African explorers, but this was extremely long ago, too long for anyone to be specific.
