So i never much worried about what my grandpa's name meant, because it is such a common name where i come from (UP of Michigan). Also, i was told once that it meant hero, but i realised later whomever told me that was confused about the name Urho, who is a character in the Kalevala, and has a pretend holiday named after him, the day before St Patrick's. I think St. Urho drove all the grasshoppers out of Finland with a drum. Tee hee.
Anyway, i can't find a meaning for the name Eino on any of the name related sites. Does anyone speak enough Finn to send me in the right direction, regarding what the word root might mean? None of my searches in Finnish-English dictionaries have come up with any words with that root.
