“The country east of the Mississippi was inhabited by a very powerful nation. * * * Those people called themselves Alligewi. * * * The Allegheny River and Mountains have been named after them. * * * The Lenni-Lenape still call the river Alligewi Sipu, the river of the Alligewi, but it is generally known by its Iroquois name–Ohe-Yu–which the French had literally translated into La Belle Riviere, The Beautiful River, though a branch of it retains the ancient name Allegheny.”
