Pierre de Beuro [? - 1790] was a French Creole. He established a trading post on the Illinois River and trading with the Indians. de Beuro was killed in an Indian attack in 1790.
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.
