Before southern Germany and Austria were German speaking they were Celtic speaking, and there are, of course, documented Celtic/Gallic migrations into northern Italy and down into Tuscany, as well as the prior Indo-European migrations of people from Central Europe who might have spoken Italo-Celtic, including my own Ligures. Looking at it from the other direction, there was a lot of Neolithic ancestry in Central Europe which arrived from the south. Where and from whom each individual trait derives I don't know, but I suspect the nose is Neolithic farmer.
As I said, the nose on the girl on the left in the first picture, on the girl in the third picture, and on the girl below is ubiquitous in the area, as are very widely spaced eyes and fair skin; I have all three traits. Where we differ from you is that we often have a squarer jawline, giving the bottom of the face a different shape, and most of us have a rounded chin.
Not that a long face with a square jaw is always present...a spray tan changes things too, but no matter the pigmentation, that combination of widely spaced long eyes, whether large or smaller, long nose broad at the tip, long face and rounded chin appears again and again, and not just in Liguria and Toscana. It's found in Campania, paired with a long thin face.
A Miss Toscana:
Miss Liguria-I think she had something done to her nose; it looks odd.
My favorite Miss Liguria and, in my opinion the most beautiful:
Miss Toscane- it's variation on a theme
I'm not saying you look Italian. I'm just saying some of your traits are definitely present south of the Alps.
On the other hand, if you look at these girls and ignore the slight differences ln pigmentation...
