Nearly all of the information on Northern New York State is during or after the revolutionary war. This page seeks to examine what was in the frontiers of northern Colonial New York state ... its settlements, population, and life between 1763 and 1790.
Onondaga and Six Nations
In Guy Johnson's 1771 map titled Country of the Six Nations, it shows a number of prominent settlements such as Shenectady and Albany. The majority of the land in 1771 appears to be in the control of the Iroquois Nation.
Encyclopedia Britannica states "In April 1779 Onondaga settlements became the initial target of a brutal American wartime campaign against the Iroquois..." and "From 1788 to 1822 the state of New York took possession of about 95 percent of Onondaga land."
If you look at Wikipedia's article on the Royal Proclamation of 1763, it shows a map of the proclamation line. That line remained in effect up until the revolution. Onondaga is firmly within Indian territory.
