A Mapp of ye Improved Part of Pensilvania in America [sic]

In 1684, William Penn requested that Thomas Holme, the surveyor-general of Pennsylvania, create a detailed map showing the progress of settlement and land ownership in the colony. Completed in 1687, A Mapp of Ye Improved Part of Pensilvania detailed the area from New Castle to about ten miles above the falls of the Delaware and as far west as the Brandywine Creek. Holme's map also included the name of each landowner within the outlines of their property. Upon its completion, William Penn had A Mapp of Ye Improved Part of Pensilvania printed and engraved in London, hoping it would entice more settlers to the colony.
