Adam Rosenstengel, a thrifty, thorough-going farmer of Pendleton Township, is the son of George Rosentengel who was born in Germany. He was married to Miss Louisa Bauman, who bore him six children, Adam Rosenstengel being the second child. The later attended school until twenty years of age, and came to America at the age of twenty-four. Four years later he married Miss Rebecca Cowhorn, and to them were born a large family of children, fifteen in number, nine of whom are still living: George, Louisa (wife of William Turpin), Mary Jane (wife of William Myers), Joshua Adam (a blacksmith), Christine (wife of Mort Robertson), John Henry, Caroline, Ernest and William. Adam Rosenstengel settled in Missouri in 1844 and worked in the mines for two years. He then located on a farm at the eastern foot of Ozark Mountains, where he now owns a fertile farm of 187 acres. He has seen a great deal of pioneer life, and says that when he first settled here the deer were so numerous as to be disastrous to crops. He is one of the old settlers of St. Francois County, and is an honest, upright citizen. His land comes within half a mile of Doe Run Lead Mines, and he was the first man to discover lead at that mine. He has also discovered ore on his own land. Mr. Rosenstengel is a member of the Lutheran Church and is politically a liberal Republican. During the Rebellion he was enrolled in Company B. of the State Militia and at the time of the battle of Pilot Knob was on the force that burned the bridges.
