Early map of Ritchie County – the green I THINK shows Grant District boundaries…. probably circa 1870s or ? NOTE the “Oil Region” between Petroleum and Volcano, the road is titled “N. Western Pike” and the Railroad comes into Cairo WITH the narrow gage shown going toward the Ritchie Mines (it was not the C&K yet) AND the P.O. (Post Office a bit west of Petroleum is name ROGERS – which existed only a very short time. There does not seem to be much more showing in the district at this early time….
