Incidentally, Dr. Wallace in his _Conrad Weiser_ assesses one John Henry Lydius with the major responsibility for the Indian massacres in central and northeastern Pennsylvania. Wallace notes that Lydius' Connecticut purchase from the Indians in 1754 caused "war between Pennsylvania and Connecticut and ... [precipitated] the Massacre of Wyoming in 1778." This massacre, as West Branch historians know, had its subsequent impact on the West Branch Valley in the Great Runaway, although the Winters Massacre of June 10, 1778, which prompted the evacuation of the valley, actually preceded the Wyoming affair.[17] Finally, the purchase of the remaining Indian lands in Pennsylvania (except for the small corner of the Erie Triangle) was made on October 3, 1784, in a second Stanwix Treaty. This accession ended the Pennsylvania boundary dispute with the Six Nations; and it also ended the need for any extra-legal system of government in the West Branch Valley, for this new treaty encompassed the Fair Play territory.[18] However, this treaty raised the troublesome Tiadaghton question once again, a question only partly resolved by the Legislature's designation of Lycoming Creek as the Tiadaghton and the recognition of the squatters' right of pre-emption to their settlements along the West Branch of the Susquehanna.[19] The land office was opened for the sale of this purchase July 1, 1785; by 1786 fifty heads of families were listed for State taxes in Northumberland County.[20] Approximately fifty per cent of these taxables had been in the area earlier. 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.
