Oswald

Im searching Oswald family.

Im searching Oswald family maybe from Chicago. The name of their great grandfather was Josef or Joseph Oswald. He was born 12 th November 1872 in Stichov or Stich, Bohemia. He had min. 6 children. I know names only of 3 of them: Jaroslav (maybe Gerald or Jerald) – firstborn son. Berta (or Bertha) and Eliska (or Elsie). Josef came to USA as single shoemaker around the year 1890. Any information will be welcome.Thanks.
