I am seeking any information on Frank and Barbara Ptacek, who came over from Czechoslovakia in 1914. They settled in Chicago and were living there on 18th Avenue by the time of the 1920 census. Apparently, Barbara was significantly older than Frank, but she is listed as his wife on both the census and the manifest of the German registry ship they came on. They were the apparent sponsors for their three nieces (Anna, Maria, and Ludmila (Sarman[ova]) who came to this country. Please help!
