My grandmother was a Lehnig and came to America in 1925 and live with her Aunt and Uncle in Bourbonnais, Illinois. They sponsored four oF August Lehnig's children when they came to America in 1925. I think these Lehnig's are the same aunt and uncle she was referring to. Your great grandfather's name was Robert Lehnig too? My grandmother's father's name was August Lehnig. He was born in Kanth Germany in 1876. He was the youngest child. I think he had another brother by the name of Paul that lived in Chicago. Do you happen to know who you great grandfather's parents' were?
