Wenrohronon

North to south, it is likely their lands extended up from Lake Ontario farther southerly more than the approximately 26 miles (42 km) shown on the map, possibly to the drainage divide (and Genesee River gorge area) formed atop the terminal moraine left behind by the Laurentide Ice Sheet, but in all likelihood, into a shared hunting ground shared with the Erie tribes near the headwaters of the Allegheny River.

While not well known today even as a tribal name in the aftermath of becoming extinct during generations-long plagues and near continuous internecine warfare, the Wenro People are known primarily through the mentions in the decades the Jesuit Relations were published.

The tribe's villages the Missionaries describe seem to have been reduced to relatively fewer permanent settlements than their neighbors by internecine warfare in the late 16th century before becoming known to the few French who encountered them.

The editors of American Heritage Magazine writing in the American Heritage Book of Indians suggested the French visitors encountered the Wenro people shortly after they had lost an internecine war, probably with the Senecas, accounting for the relatively small size of their territory,[2] as they were on fair terms with the Erie[2] and good terms with both the Neutrals and Huron[2] at that time, and the Susquehannocks were both remote and have little to compete over in consequence.

[4] Later in the 1640s-1650s,[2] after the Beaver Wars turned genocidal, they had a falling-out with their former allies, the Neutrals, which made it impossible for the Wenros to withstand their long-time enemies, the Iroquois.

The French missionaries monitoring first people in 1630s report the Wenro's territory was north and east of the Erie peoples , East of the Neutral people across the Niagara River and west of the Genesee River valley and the Genesee Gorge across which the Seneca people had their home.

Amerindian boundaries, such as they had use to understand, would likely have been defined along water courses, and ridgelines (i.e. Drainage divides , unlike the southern border approximated by the neat lines above); their famed oil spring , for example, was well south of the marked territory.
