It is possible that my half Great-Uncle changed his name from Frank Krupicka, Jr. to his mother's maiden name: Burda in the late 1890's or early 1900's. Frank was born Frantisek BURDA on 23 Nov 1885 in Brzotice no. 13 in Bohemia. When he immigrated with his father, Frantisek (Frank) Krupicka, he used the name Frank Krupicka, Jr. Probably settled in Chicago area. Any information from Chicago area descendants?? I have a bit more information on Frank from my researcher in Prague.
