I am related to a Joseph Capek from Cleveland, Ohio (my great grandfather). There isn't too much known about his side of the family, the most I know is that he had a brother named Henry. His side didn't speak to him too much after he married the daughter of German imigrants (Anna Zimmerman) in 1917. They had three children, Walter (my grandfather), Raymond, and Helen. I know that some of my relatives moved to Chicago (some of my grandfathers cousins). I hope this is some help.
