AKWESASNE -- Crazy Horse family elder Floyd Clown Sr. will join author William Matson to discuss and sign their book "Crazy Horse: The Lakota Warrior's Life and Legacy" Tuesday, Oct. 15, from 5-7 p.m. at the Akwesasne Cultural Library, 321 State Route 37.

The book is based on the Crazy Horse family’s oral history, said a press release from Matson.

This will be their landmark 274th appearance as they travel across the United States and Europe, the press release said.

The Crazy Horse family's oral history had not been told outside the family for over a century because the government had been hunting their family members since Crazy Horse was assassinated in 1877, the press release said. Now, over a century later, it is finally being told by his family.

Clown, a son to Edward Clown who was a nephew to Crazy Horse and keeper of the sacred bundle and pipe, will represent his family at the discussion.

Books will be available at the signing.

Clown currently lives in Dupree, S.D. on the Cheyenne River Reservation.

Matson, a documentary film maker, currently resides in Spearfish, S.D. This is Matson's first book.

The event is free and open to the public.
