[Ganondagon, referred to by Greenhalgh as Canagaroh, was a Native American settlement of the Seneca people in western colonial New York.  Greenhalgh travelled to the area to secure the Seneca as allies for the British] 

Observations of Wentworth Greenhalgh in a journey from Albany to the Indians westward begun 28th May and ended 14th July 1677 […] Being at this place [Tiotehatton] 17th June, there came 50 [Native American] prisoners from the south, of two nations, some whereof have few guns, the other none at all; one nation is about 10 day's journey from any Christians and trade only with one great house not far from the sea, the other trade only, as they say, with a black people; two women and a man were burnt on that day and a child killed with a stone; at night there was a great noise as if the houses had fallen, but it was only the inhabitants driving away the ghosts of the murdered. On the 18th, going to Canagaroh, overtook the prisoners; when the soldiers saw us they stopped each his prisoner and made him sing, and cut off their fingers and slashed their bodies with a knife, and when they had sung each man confessed how many in his time he had killed[.]
