"Guy C. Irvine was born December 15, 1792, he came to Warren County about 1815. He bought a sawmill in 1817, and formed a partnership in another sawmill in 1818, embarking on a lumbering career that made him famous on the rivers from Olean to New Orleans. In 1822, he married and lived in a log cabin with his bride. In 1826 he was cutting 3,000,000 feet of pine lumber every year, and owned numerous mills and hundreds of acres of timber. In February, 1834, the Lumberman’s Bank of Warren was incorporated by an act of the State Legislature. Guy C. Irvine was one of six commissioners appointed to execute the act. He built a brick mansion in 1835, now known as “The Locusts”, and also a stone grist mill in 1836. The farm consisted of 359 acres. He was a high tempered, exacting man, never at ease, rough and rugged, but very soft hearted and always open and above board. He was respected by his employees in the woods and on the rivers. He had a grist mill and gang sawmill at Irvine Mills on the Conewango, and a four mile railroad supplying the sawmill. He was a typical frontiersman, big and strong; he never backed away from a fight or brawl. He was a friend of Philip Tome, the hunter. He died in 1868 at age 76."
