JOHN M. SHOCK, M. D.
Dr. John M. Shock is a native of Boone county, Missouri. He is the son of David S. Shock, one of the early and substantial pioneers, a Kentuckian by birth, and a native of Fayette county. The father of David Shock was a Virginian and a soldier under *Mad Anthony Wayne," in his famous campaign against the French and Indians. He remained in the army for three years. The Shocks are of French origin. The father and 2:grandfather of Dr. Shock were members of the regular Baptist church. The subject of this biography was born one and a half miles north of Columbia, August 16th, 1824. He was brought up on the farm and attended the common schools of the country, which in his day were none of the best, but by close application he mastered the studies then taught in our district schools and became a teacher. After six years of diligent labor in the school room, he attended Pope's Medical, College in St. Louis, where he graduated in 1858. Returning from St. Louis, he commenced the practice of his profession in the neighborhood where he now resides. He has had all the practice he could attend to in the last quarter of a century. He is still in the prime of vigorous manhood, and at this writing is equal to the labor of the busiest year of his life. He has prospered in business almost from the start. He owns over five hundred acres of very fine land besides other valuable property. He was married in 1852 to Miss Sallie A. Sheley daughter of Ransom Sheley, of Callaway county, Missouri. One child was born of this marriage. The first wife died three years after marriage and the doctor those for his second wife Miss Catherine Ritchie, of Kentucky. She died in 1860*, leaving one child. He was married the third time to Miss Sallie J. M. Mc- Quitty, daughter of George McQuitty, a prominent farmer of Boone county. They have four children by this marriage, one son and three daughters. Dr. Shock is a zealous and influential member of the Baptist church and a teacher in the Walnut Grove Sunday school. He is a member of the Everett Grange, also a member of the Rocheport lodge of A. F. & A. M. His life has been a success. He is, in the strictest sense of the term, a self-made man.
