In 1945, she began writing
The Ten Grandmothers with her frequent collaborator, archaeologist Carol K. Rachlin, for the
University of Oklahoma Press. Eight more solo books on Native American and Southwestern topics followed in 1953. Marriott published a biography,
Sequoyah: Leader of the Cherokees, in 1956 and
Black Stone Knife in 1956. In 1968 she published with Carol K. Rachlin
American Indian Mythology, and in 1971 she also published, with Rachlin, the book Peyote, through the now-absorbed-by-Harper & Row publishing house Thomas Y. Crowell Co. The authors advertised the book as "A compelling study of the sacramental use of the Native American hallucinogen." As a freelancer, she continued to write, producing three more books with Rachlin by 1975. == Awards and honors ==
