At the Hillsborough Township Municipal Building, you will find, prominently displayed, the 1860 Farm Map of Hillsborough. Here is a portion of the map.
By 1876, this map would be radically changed. Do you know why? Here's a hint: In 1865 there was one, by 1872 there were three, by 1876 there were four - then back to three by 1880, and today we have two.
