The father of the bill creating Grundy County was William E. Armstrong and he was an ardent admirer of Felix Grundy, the greatest criminal lawyer Tennessee ever had, and the Attorney General of the United States. Through Mr. Armstrong's influence the new county was named Grundy although it is doubtful the famous lawyer ever set foot inside its boundaries.
LaSalle County FYI
LaSalle county was named after Robert de la Salle, a French explorer who sailed down the Mississippi River to the Gulf of Mexico and claimed the region for France. De la Salle, was responsible for the first European settlements in the area.
LaSalle County was originally part of Putnam County, which had been established in 1825. In 1831, LaSalle County covered parts of present-day Kendall, Livingston, and Marshall Counties, and the entirety of present-day Grundy County. The current boundaries of LaSalle County were established in 1843.
