To follow further the topic of this chapter one may have recourse to Heckewelder and study his etymology as far as applicable to local geographic names. Some annotated extracts from his book, "Names, etc.," are:[2]

ALLEGHENY—According to Heckewelder, is a name corrupted from Alligewi, the ancient tribe that the Delaware traditions declare once dwelt along the river's bank. The word can have been evolved from the Delaware term Alligewinink, signifying all the country west of the Allegheny Mountains drained by the tributaries of the Ohio, and their numerous sources. The Shawanese called this river Palawu-thepiki. The French applied the appellation La Belle Riviere to this river and subsequently to the Ohio, regarding the Allegheny as not a tributary, but the main stream of the great river of the Alligewinink. The Delawares called it Kit-hanne, it being the same descriptive appellation by which they had designated the great river from which they took their English tribal name. To the Delawares the term meant that the river was the main stream in the region of country through which it ran. English traders on the river as early as 1731 reported that there dwelt on the Kittanning river mostly Delawares, fifty families, one hundred men with their chief, Ky-ken-hammo. Kit-hanne is a corruption of the Minsi name Gicht-hanne; the other Delawares called the Delaware river Lenape-wihittuck.
