WILLIAM G. DUNCAN, superintendent of McHenry Mines, postmaster and express agent, Ohio County, is the son of Andrew Duncan, a native of Glasgow, Scotland, who came to America in 1855, and first settled in Pottsville, Penn. He remained there but a short time, however, but went to Airdrie, Muhlenbergh Co., Ky. Being a practical miner he took a contract to sink a shaft for R. S. C. A. Alexander, at Airdrie, Ky. Afterward he opened a mine at Paradise, and then went to Butler County, Aberdeen. Twelve years ago he came to McHenry and opened the first mine, becoming one of the owners, and was superintendent until his death, which occurred May 25, 1877. His widow is still living at McHenry. They had eight children, of whom William G. Duncan is the eldest, and was born in Hollytown, Scotland, September 4, 1851; Mary, wife of Oliver C. Roll; Jennie, wife of W. D. Hamilton; D. S. Duncan, druggist, at McHenry Mines; Andrew J., late superintendent of Echols Mine, killed at the age of twenty-one, October 23, 1882; Jennette; Ella; and Maggie. Mr. Duncan was married May 16, 1878, to Mary H., youngest daughter of William Hamilton, also of Glasgow, Scotland. Mrs. Duncan was born in Airdrie, Ky., October 12, 1860. They have two children: Katie Belle, born May 13, 1879, and Andrew Wallace, born July 27, 1880. Mr. Duncan began mining at the age of twelve years, and is a practical miner, thoroughly understanding all parts of the business. He is now one of the three owners of the mines, and is also secretary and superintendent. Mr. Duncan is a self-made man, honest and upright in all his business relations, and has the highest reputation in both commercial and social circles.
