I'm looking for my great grand father Contantine Listed in 1920 Censu Konstante B. Graczyk. He went by Gus, was born in Chicago Illinois, south side. Born 12/13/1890, was drafted into WWI in1917. Originally worked for the Railroad, and invented something for the Pullman Standard company, but I can't find out what. Possible had 2 brothers Andrew, Alex, and Stanley. His wife Martha, moved out to her daughter's home, Florence and was never heard from again. Florence is my grandmother who is turning 89 this December and I was love to tell her what happend to her father. Last contact with the family was about 1940. He had a history of alchohol use and gambling. It is unsure if he ever divorced his wife Martha. Any info would be helpful. Thanks
