For more than eighty years after William Penn received his grant for Pennsylvania, the Penn and the Calvert families found themselves embroiled in bitter disputes over the boundaries between Pennsylvania and Maryland. In 1731, attorney Ferdinando John Paris was solicited to act as mediator between the two parties. In order to determine mutually agreeable boundaries, each side was asked to produce maps to be used in the negotiations that took place in London. As a result, London cartographer John Senex was commissioned to produce this map. The boundary line between Pennsylvania and Maryland was not resolved until Charles Mason and Jeremiah Dixon completed their survey in 1768. Literature: Pritchard, Margaret B. and Henry G.
