JOHN G. HENDERSON, a prominent attorney of Carrollton, was born near White Hall, Greene county, Ill., Sept. 22, 1837. His father, John P. Henderson, was a native of Kentucky, and a son of Rev. John Henderson, one of pioneer Christian preachers, of Greene county. His mother, Susan (Green) Henderson, was a native of Ohio. John G. spent his early life on the farm. He was educated in Jacksonville, Ill., and subsequently taught school during which time he also studied law. He afterwards read law with John L. McConnell, of Jacksonville, and on the 10th of Aug., 1858, though not yet 21 years of age, was admitted to the bar at Jacksonville, to practice in Illinois. He subsequently practiced law, and also taught school, in Morgan county, until 1861, when he opened a law office at Griggsville, Pike county, and entered upon the duties of the legal profession in earnest. But he afterwards engaged at teaching for a while, his last term being taught in 1863, at Naples, Scott county, where he practiced law until 1866. He then located at Winchester, and in 1877 was elected county judge of Scott county, serving in that capacity five years. Since that time he has given his entire attention to the legal profession, practicing in both Scott and Greene counties, and his practice increased so largely in Greene county, he decided to remove to Carrollton, which he did in Feb., 1884, and his office and residence are now there, although he still practices in Scott county, during each term of court. He was married April 10, 1884, to Isabel Springer, nee Hanback. In 1878, at the St. Louis meeting of the American Association, of Science, Judge Henderson became a member, and for two years, was secretary of the anthropological sub-section of the association, and at the Boston meeting was elected a fellow of the association. He has written for that society several papers, mostly on the subject of anthropology, of which he has made a life study, and has accumulated a fine library of works on that particular subject. He is also said to possess the finest library in the Mississippi valley, of French and Spanish works on the early history of said valley. He has now, at the point of completion, a work on ancient names of the United States and British provinces, which has occupied much of his time for the past 20 years. Politically speaking, he is an active democrat, and has taken a prominent part in politics since he attained his majority. Judge Henderson is a member of the Illinois Natural History Society, and an honorary member of the St. Louis Historical Society. Several of his articles have been published by the Southwestern Society, under which institute he has done considerable scientific research.
