My grandfather's sister Hertha Gast married Ernest Bahls in the early 1900's probably in Chicago (she was born in Chicago and lived there all her life). They lived in Chicago from then on. Their children were George (1914) and Edna (1917). My research has shown that Ernest was born 6 March 1881 in Berlin, Germany. He emigrated from Berlin in 1906. Does this sound familiar to anyone?
