Marie L. McLaughlin

Born in 1842, she is also identified as Marie Louise Buisson and later Marie Louise McLaughlin. Public-domain library records and author listings connect her with Myths and Legends of the Sioux, published in 1916, and describe her as a folklorist of the Sioux.

That book is dedicated to her mother, Mary Graham Buisson, and says many of the stories were told to her in childhood. That detail helps explain the personal, rooted quality of her writing: rather than presenting folklore as something distant, she wrote as someone shaped by the stories herself.

Wikisource lists her lifespan as 1842–1924. A clear, verified portrait could not be confirmed from the available Wikipedia page results, so no profile image is included.
