Perhaps the only significant nationality trend to be noted in this important sequence of events is the tenacity of the Scotch-Irish and the subsequent increase of English and German settlers following this last "New Purchase."[21] Over half of the taxables in Pine Creek Township, the new designation for much of the Fair Play territory after it became an official part of the Province, were Scotch-Irish. As a result, these Scots from the north of Ireland continued to maintain their position of leadership even after the area was included in the Commonwealth.
The reasons for migrating to the West Branch Valley in this fifteen-year period from 1769 to 1784 were varied and numerous. For the most part, the various nationality groups which emigrated from Europe came for economic opportunity and because of religious and political persecutions. Their movement to the frontier regions was prompted by similar problems. In fact, much the same as the earlier settlers of Jamestown and Plymouth, the squatters of the West Branch Valley came for gain and for God. Furthermore, the promise of Penn's "Holy Experiment," in which men of diverse backgrounds could live together peacefully in religious freedom and political equality, encouraged them to come to Pennsylvania. However, once the dominant group of the Fair Play frontier, the Scotch-Irish, arrived in Pennsylvania, they found themselves unsuited to the settled areas. The natural enemy of the English, who had oppressed them at home, these settlers soon found themselves repeating the Old World conflicts. In addition, the German Pietists caused them further embarrassment in their new homes. Their Calvinism, fierce political independence, and earnest desire for land and opportunity soon made them _personae non gratae_ in the established areas. Hence, they migrated to the frontier areas and even beyond the limits of Provincial interference and control.[22]
The paucity of population data makes impossible any extensive analysis of the stability and mobility of the Fair Play settlers. However, the tax lists, both in the published archives and in the files of the county commissioners in Northumberland County, offer limited evidence for the early years, though they provide ample data for the years after 1773. Prior to the Great Runaway in 1778, tax lists are available for the entire county of Northumberland; the lists simply indicate the taxable's township, acreage, and tax. Records in the Northumberland County courthouse give the assessments for 1773, 1774, 1776, and 1778.
