Interesting. My mother was a Balis and one of 5 children who grew up in Philadelphia, PA. Her father was Clarence Wanton Balis. Her mother was Margaret Otis, sister of the mother of Ameila Earhart (Amy Otis). We don't know much about our grandfather, Clarence Wanton Balis, except that I believe he grew up in New York State. Not sure if this is a relative of the individuals in your photos, but the name Clarence Balis caught my eye.
