Hi, I researching the above name. My grandmother, Ida Wilke (WLK at the time) was born in 1879 in Reichenberg (now Liberec) Bohemia. Her parents were Joseph Frank WLK b.1846 Jirsko and Karolina Anna Pilz b.1844 Altharzdorf. My grandmother's name changed toWilke when she moved to Germany--the German's couldn't pronounce WLK. If anyone has add'l info please contact me. Thanks, Nancy R.
