Frederick Town” was laid out by Daniel Dulany — a land speculator — in 1745;it was settled by a German immigrant party led by a young German Reformed schoolmaster from the Rhineland Palatinate named Johann Thomas Schley (d. 1790), who came to the Maryland colony with his wife, Maria Winz. Schley built the first house of the new town; as late as the 20th century, it stood at the northwest corner of Middle Alley and East Patrick Street. The settlement was founded upon a tract of land granted by Dulany on the banks of Carroll Creek. Within three years, the settlement had become the county seat of Frederick County. It is uncertain which Frederick the town was named for, but the likeliest candidates are Frederick Calvert, 6th Baron Baltimore , Frederick Louis, Prince of Wales, and Frederick "The Great" of Prussia. Most sources favor Calvert. Come On Down!!!
