My mother was born at Pennville SD, which I believe was in the northern part of Harding County. I would like to known where Pennville was located. How far was it from Ralph. My Grandfather Celia Millar Smith had a homestead near Pennville. I would like to find out where it was. We were always told Pennville was in Perkins County. However I was recently told the homestead was in Harding County about 20-30 miles west of Ellingson, Perkins County, SD
