You look Galician to me. Galicians are Poles who have "moon faces" and parts of the region spoke Ukrainian, Lithuanian and a Ruthenian dialect. That could be your mystery language. If you know your grandmother's maiden name or the name she had when she arrived in the US, it wouldn't be hard to find out where she's from. You can email the information to me and I'd be happy to look it up for you.
