The populated area today known as Hillsdale took form in the mid-to-late 19th century as land speculators, led by David P. Patterson, developed subdivisons to profit from the coming of the Hackensack and New York Railroad (later New Jersey and New York Railroad).
Gap is a census-designated place and town in Salisbury Township, Lancaster County, Pennsylvania with a zip code of 17527. The population was 1,611 at the 2000 census. It is the terminus for four Pennsylvania highways: 772, 741, 897, and the heavily-used 41, which goes toward Wilmington, DE.
