Thank you for your reply. Not sure if your line is related unless your John is 1) Charles father, John, from Prussia, or 2) Charles' son, John, b. 1886, in Chicago. Since my last message, I have discoved additional information.Let me know if the following is helpful regarding your Bartz line.
Charles Bartz, born Dec 1856, came from Germany, (naturalized around 1875), and lived in Chicago, Ill.Per a 1900 census record, he had 6 known children-- Bertha, b. Aug 1881, Gilliam, b. Jul 1882, Charles, b. May 1884, John, b. 1886, Lucy, b. Apr 1890, and Bernard, b. Mar 1893. His son Charles, (my great-grandfather), moved to Wisconsin around 1910.
I was able to locate a census record from 1880 that shows a Charles Bartz from Prussia, age. 24, residing with his mother, Phillipine Bartz, age 48, and his siblings, Frank, 21, Bertha, 14, Minnie, 11, and Anne, 6, in La Crosse, Wisconsin. A prior record from 1870, lists the same family but adds a father, John, from Prussia, age. 46, and another sister, Theresa, age. 8 mo.Not sure if this family is related to yours or mine. If you or anyone has any information, please advise.Thanks.
