I am seeking the names of my grandmother's parents and siblings, and also her birthplace in Illinois. Dora (later Dorothy) Dettlaff (var. Detlaff, Detlof) married my grandfather Vincent Kuszynski on 09 November 1908 at the age of 20 (per "Illinois, Cook County Marriages, 1871-1920"). I have found Dora in the 1910, 1920, 1930 and 1940 federal censuses, and she died on 10 February 1950, in Cook County. According to census records, she was born in Illinois and her parents were from Poland. Dora and Vincent had five children: Stanley, Edward, Frank, Florence and Chester.
Thank you for any information you can offer on Dora Dettlaff''s parents, siblings, or birthplace. I, in turn, am happy to share what information I have.
