Anna Dostal in Iowa
John Shonka married Anna Dostal. I believe Anna is the daughter of Joseph Dostal II and Anna Salacek.They had a son, John R Shonka born in 1875. They also had sons named William and Joseph.
John R. Sonka married Frances Shramek around 1900. They had children named Tillie, Godfrey, Leo, Lucile, Jerome, and Frances. John R. appears to be the first Shonka to go by "Sonka".
