History of Jo Daviess County

Jo Daviess County was formed in 1827 out of Henry and Putnam counties. It is named for Maj. Joseph Hamilton Daveiss, United States Attorney for Kentucky, who was killed in 1811 at the Battle of Tippecanoe. The local pronunciation is "Davis". Jo Daviess County was founded exclusively by immigrants from New England. These were old stock "Yankee" immigrants, meaning they were descended from the English Puritans who settled New England in the 1600s. The completion of the Erie Canal caused a surge in New England immigration to what was then the Northwest Territory. The end of the Black Hawk War led to an additional surge of immigration, once again coming almost exclusively from the six New England states as a result of overpopulation combined with land shortages in that region.
