John Greyeyes, whose Wyandot name was Hehn-toh, or “He Leads” was a member of the Little Turtle Clan. He was the son of Esquire Greyeyes, and grandson of Doctor Greyeyes. John was an attorney, served as Acting Principal Chief, and was a long-time councilor to the Wyandot nation.
Greyeyes was educated at a Mission school in Upper Sandusky and later attended Kenyon College in Ohio. He graduated with high honors and was admitted to the Ohio bar. He represented the Wyandot for several years in Washington. Greyeyes arrived in Kansas in 1843 with the rest of the Wyandots and built a hewed log house on the west side of what is now Third Street, which afterward became part of the residence of Joel Walker. He lived there with his wife Catherine Greyeyes. In October 1851, the Wyandots adopted a new tribal constitution that formally codified the various changes in the structure of tribal government. It was drafted by an elected committee of 13 delegates including Esquire Greyeyes. In 1851- 1852, John Greyeyes served on the tribal council and was appointed to go to Department of the Interior in Washington D. C. to secure the funds appropriated for them in the Treaty of 1867.
Greyeyes became head chief when Tauromee died in 1870. He served in this role when the Wyandots who had rejected U. S. citizenship moved to Oklahoma. In 1881, he was the last living Wyandot who had signed the treaty of 1867. Greyeyes died on the Wyandot Reservation near Seneca, Missouri and is buried at Wyandotte, Oklahoma.
