I'm looking for information about my grandmother, Frances (perhaps originally Franceska) Striegel, possibly from Keokuk county. Her husband, Thomas C. Burke, came (I think) from that county. She was born in the 1860s or 1870s. She was a concert pianist, and studied in Chicago and in Vienna. She had a brother, Louis, who became a newspaper editor in St Louis. She died in Portland, Oregon in 1933.
