A. S.  ROBERTSON,  physician, P. O. Pin Oak, was born  in Lawrence County, Ohio, July 9, 1830, and is a son of David and Rebecca (Clark)  Robertson.  The father was a native of Virginia, the  grandfather coming to this country from Scotland, and the grandmother from Ireland.  The mother of our subject was born in New jersey, and in that State her parents were also born.  Subject was the fourth of nine children, of whom seven are living.  His education was very limited, for untild he was seventeen he spent his spare time in assisting his father on the home farm.  At that age, he commenced reading medicine with Dr. L. McCook, of Lawrence County, Ohio.  He only read with him about eighteen months, and then commenced the active practice of medicine.  As he advanced in years, he enlarged his fund of information, and pursued his course of study  farther and farther.  He practiced in parts of Ohio, Kentucky, Indiana, and finally came to Hardin County, Ill.  After a short stay there, he came to Macoupin County.  In that county, he practiced for about two years, and then in November, 1862, he came to Wayne County.  The Doctor first settled in Four Mile Township.  There he practiced some six years, and then came to Arrington Township, where he has since practiced.  Our subject is truly what might be called a self-made man.  His whole knowledge of medicine has been obtained by his own exertions, and outside of the walls of any medical college, and he is well  worthy of the extensive practice that he enjoys from the people of Wayne County.  Dr. Robertson was married, in December 1864, to Sarah A. Warren.  She is a native of this county, being born here October 23, 1844, and is a daughter of William and Minerva (Gaston) Warren, who were natives of Illinois.  Five children, three girls and two boys, have blessed this union, of whom three are now living -- Idella, born September 30, 1866; Athalia, August 1, 1868; Amos T,  January 27, 1871.  Rebecca J., born January 18, 1874, died October 24, 1879;  William D, born September 22, 1880, died September 14, 1882.  Subject is a member of Middleton Lodge, No. 82, I.O.O.F.  In politics, he is a Republican.
