88611 Teharonhiawako           Discovered 2001 Aug. 20 by the Deep Ecliptic Survey.
In the Haudenosaunee (Iroquois) creation myth Teharonhiawako was a son of the granddaughter of the Great Spirit creation god. He became a farmer and was loved by the people. The companion object (88611) Teharonhiawako I, discovered 2001 Oct. 11 by J. L. Elliot, S. D. Kern and D. J. Osip, is named for his twin brother Sawiskera. Sawiskera was a skilled hunter but was jealous, cruel and destructive, and he was eventually conquered by his brother. The names were suggested by R. J. Benecchi and S. D. Kern.
