 Examined historic maps (Griffith 1795; Bond 1858; Martenet 1865, 1885; Lake 1873; USGS1910) depict Jefferson on what is now MD 180 as early as 1795.It was designated "Trap Town" at the close of the 18th century by Griffith (1795).Local history suggests that the name derives from the large number of taverns operating at the time, which were purportedly, on either ends of town.
