Kenesaw Mountain Landis was born in Millville, Ohio, the sixth child and fourth son of Abraham Hoch Landis, a physician, and Mary Kumler Landis, on November 20, 1866. The Landises descended from Swiss Mennonites who had emigrated to Alsace before coming to the United States. Abraham Landis had been wounded fighting on the Union side at the Battle of Kennesaw Mountain in Georgia, and when his parents proved unable to agree on a name for the new baby, Mary Landis proposed that they call him Kenesaw Mountain. At the time, both spellings of "Kenesaw" were used, but in the course of time, "Kennesaw Mountain" became the accepted spelling of the battle site.
