JOHN J. BROWN, M. D.
Dr. Brown is a son of John and Ellen {nee Henderson) Brown, both of his parents being natives of Virginia. He was born in Rockcastle county, Kentucky, February 5, 1847, and grew up in his native county, receiving his education in St. Mary's College and the University of Kentucky. Early in life he began the study of medicine. In 1866 and 1867 he attended the medical college at Cincinnati, Ohio, and on leaving there began the practice at Mt. Vernon, near where he was born. In 187-5, he entered the medical department of the State Universit;% returning to Mt. Vernon and resuming his old practice after he took his degree of M. D. in 1876. He was appointed the same year by Got. McCrary to serve as official examiner for the fifteenth district, to pass upon applicants who desired to practice medicine before graduating from a chartered college of medicine. For eight years Dr. Brown filled the office of county school commissioner in his native county. He was married December 15, 1867, to Miss Mollie E. Snodgrass, a native of the same county as himself. They have seven children, all living at this writing. In the fall of 1882, Dr. Brown came to Green county, locating at Bois D'Arc. So well-informed and experienced a physician will, doubtless, win for himself that full share of the professional practice which his ability and general fitness so fully merit.
