My great uncle moved to Chicago from the Madison, WI area around the turn of the century and, basically, disappeared!
I know he was still alive in the early 1930's and that he had a son named Ernest. Frank, Mary, George and Ernest are listed on the 1920 US Census living in Chicago. After that,
I have absolutely nothing! Frank was born in 1872 in Bohemia. His parents were Bartholomew and Mary Hruby, buried in Waunakee, WI. He had two younger brothers, Bartholomew, born in 1877 in Bohemia,and George born in 1880 or 1881. The family came to the US in 1880. A sister, Mary, was born in WI in 1887. My family has no further information on them.
