Alexander Barber came from Ohio to Randolph County in 1805. He was a capable and energetic man with a particular skill in building mills. For many years, his services were sought after, by those wishing to establish an industry of this type. After construction of several mills for other people, he built and operated one of his own on Mill Creek, about five miles north of Rockwood. In another way, Alexander enjoyed a rather unique distinction, serving more than forty continuous years as a Justice of the Peace.
