I consulted Eckert, turns out those Indiian raiders being pursued by the militia that subsequently committed the Gnaddenhutten atrocity really were Wyandots and such may have also been responsible for Tull Hill.

The Wyandots were/are an Iroquoian tribe (like the Six Nations and the Cherokees, most everybody else being Algonquin speakers) likely related to the Hurons and were of particularly feasome repute at that time (see... http://www.ohiohistorycentral.org/ohc/history/h_indian/tribes/wyandot.shtml , perhaps Magua in the movie "Last of the Mohicans" might better have been identified as a Wyandot).

The murdered Christian Delawares on the other hand, dressed like White people and had been forcibly relocated and confined to a new village site upon the order of neighboring tribes. Impoverished and starving, some of them had received permission to return to their old village site of Gnaddenhutten to look for unharvested crops, which is what they were doing when the Pennsyvania militia found them.
