Palmyra, PENNSYLVANIA - Post Office:  Palmyra (Pennsylvania German: Pallemschteddel) is a borough in Lebanon County, Pennsylvania, United States. It is part of the Lebanon, Pennsylvania Metropolitan Statistical Area. The population was 7,807 at the 2020 census.   It is clear that the first settlers to live near Palmyra came from two distinct nationalities, the Scotch-Irish and the German Palatinates.  The settlement's Post Office was established on April 1, 1804. The name of the town submitted to the Postal Service was “Palmstown”, in honor of Johannes Palm. Yet in 1806, there are records of a tract of land located on both sides of Main Street purchased by John Kean with the settlement being referred to as “Palmyra”, most likely referencing the Roman outpost of Palmyra in Syria. Although both names were used for a time, the popularity of “Palmyra” had spread and became the official name of the settlement by 1810.   This White Border Era (1915-30) postcard is in good condition.
