I'm stumped finding data on my great grandfather, Joseph (Josip) Stephen Klescek. I believe he was born in Jugolsavia/Serbia in 1888. Father may have been Jasper Klescek, Mother may have been Bonicin Cleslowski. He died in 1946 at the Cook County TB hospital in Cook County, Illinois, USA. He was buried in an unmarked grave at the hospital TB cemetery (now a park).
