If you were born in Switzerland, then you are Swiss (born). If your parents, and their parents, and their parents, were born in Germany, then you have German roots - or you are Swiss of German extraction.
I'm an Australian born, but I have Welsh, Irish, Scottish, English, Australian, and Swedish roots.
(Had to throw the Aussie roots in, too, as that started in 1804, and successive generations - with one exception - were born in Australia.)
