Here in Germany, EINO is extremely rare. It seems to be Scanadinavian, possibly Finnish. Now I haven't come accross one single Eino; however I met a girl by that name, whose parents told me, that they had met two more.
Now Eino as a feminine name is not listed in any of my books. – Does anybody have any information as to whether Eino is used as a feminine name in Finland or any other Scandinavian country?
