Margaret Behan

In July 2012, Behan hosted the "11th Gathering of the International Council of 13 Indigenous Grandmothers" at which the riders commemorating the Northern Cheyenne Exodus of 1878 shared stories of their journey. Initially planned to be held on her private property, wildfires led to the event being held at the pow wow grounds leased from the Northern Cheyenne Reservation. "The gathering ... [was] set up as a traditional Cheyenne encampment", with "thirteen teepees, one for each grandmother." In attendance was a great-great-great grandniece of General Custer, who made a "formal apology to the Northern Cheyenne," and a great-great-granddaughter of Brig. Gen. Anson Mills, who also offered an apology.

She was interviewed by AARP International Magazine in October, 2011.

Margaret is the founder of "The Cheyenne Elders Council", formed in 2007–2008, with Behan as the sole member, and has the mission to, "Heal Our Own Oppression." She had recently bought land next to the Northern Cheyenne Reservation, and said she "was troubled when she heard one of her people say that Cheyenne youth would have to save themselves," saying "They were not getting any kind of influence or teaching from the elders." Behan reported that she had created "the T’sistsistas’s Sacred School" in her home. Behan says, "We need to bring our Cheyenne identity and pride back to the young people, teach them the traditional ceremonies and language."

Margaret's mother-in-law, noticed how well Margaret worked on a pair of beaded moccasins and suggested that she might want to work in clay. Margaret felt so confident in her new career as an artist that she resigned from her job in 1982 and took up her new artistic career full-time. Her work is mentioned in four Folk Art books. She later moved to Taos, New Mexico due to the properties of the clay there.
