The relevance of the first Stanwix Treaty to the geographic area of this study is a matter of the utmost importance. The western boundary of that treaty in the West Branch Valley of the Susquehanna has been a source of some confusion because of the employment of the name "Tiadaghton" in the treaty to designate that boundary. The question, quite simply, is whether Pine Creek or Lycoming is the Tiadaghton. If Pine Creek is the Tiadaghton, an extra-legal political organization would have been unnecessary, for the so-called Fair Play settlers of this book would have been under Provincial jurisdiction.[7] The designation of Lycoming Creek as the Tiadaghton tends to give geographic corroboration for the Fair Play system.
First and foremost among the Pine Creek supporters is John Meginness, the nineteenth-century historian of the West Branch Valley. His work is undoubtedly the most often quoted source of information on the West Branch Valley of the Susquehanna, and rightfully so. Although he wrote when standards of documentation were lax and relied to an extent upon local legendry as related by aged residents, Meginness' views have a general validity. However, there is some question regarding his judgment concerning the boundary issue.
Quoting directly from the journal of Moravian Bishop Augustus Spangenburg, who visited the West Branch Valley in 1745 in the company of Conrad Weiser, David Zeisberger, and John Schebosh, Meginness describes the Bishop's travel from Montoursville, or Ostonwaken as the Indians called it, to the "Limping Messenger," or "Diadachton Creek," where the party camped for the night.[8] It is interesting to note that the Moravian journalist refers here to Lycoming Creek as the Tiadaghton, some twenty-three years prior to the purchase at Fort Stanwix, which made the question a local issue. Yet Meginness, in a footnote written better than a hundred years later, says that "It afterwards turned out that the true _Diadachton_ or _Tiadachton_, was what is now known as Pine Creek."[9]
Perhaps Meginness was influenced by the aged sources of some of his accounts. It may be, however, that he was merely repeating the judgment of an earlier generation which had sought to legalize its settlement made prior to the second Stanwix Treaty. The Indian description of the boundary line in the Fort Stanwix Treaty of 1768 may also have had some impact upon Meginness. Regardless, a comparison of data, pro and con, will demonstrate that the Tiadaghton is Lycoming Creek.
