This act was signed on February 13, 1808. It created Preble County along the Ohio-Indiana border out of portions of Montgomery and Butler counties. Preble County was named in honor of Edward Preble, a U.S. naval officer and commander during the Revolutionary War. Capt. Edward Preble commanded the US naval frigate Constitution from 1803–1807 as head of the Navy’s 3rd Squadron during the United State’s confrontation with Morocco and the Barbary pirates, who harassed American merchant ships in the Mediterranean
