My great grandfather was Mathew Hanzlik (often called Matt or Mike)and he married Anna Dvorsak. I don't know if the combination of these two names is coincidental or if we have a connection back a few generations.
Mathew was born in 1856 in Bohemia or Austria-Bohemia to Kasper and Anna Chan Hanzlik. They emigrated to the United States in 1869 and settled in the Douglas County/Pope County area in Minnesota. Mathew did not have a sister named Anna.
In 1880, Mathew married Anna Dvorsak in Pope County, MN. Anna was the daughter of John and Katherina Chorvat Dvorsak and was born in 1857 in Kewaunee County, WI. She apparently migrated from WI to MN in 1880. She did not have a brother named Jakub.
