Here is the Lancaster County Courthouse, as seen in the 1875 Historical Atlas of Lancaster County. The publication was compiled by the famous cartographer Major L. H. Everts of Geneva, Illinois, who, in 1865, joined a partnership with his Civil War comrade, Captain. T. H. Thompson.
Major Everts was reportedly remarkably suited for this work. A guide to atlas and map publishing described Everts as “smart, active, genial, penetrating in his observation, sanguine of success, enthusiastic and an unusual judge of human nature. He knew at a glance how to approach a man, and was able to discover the soft spot in his head in an instant. He always left his ‘victim’ feeling in excellent humor with himself and satisfied that no one had ever before fully realized what a capital fellow he was. But Everts almost always carried away in his pocket the gentleman’s signature for a map.”
