around the world—leprechauns, brownies, gnomes, and dwarves. American Native tribes also had stories of little people.
Among the Choctaw these beings were called Kowi Anukasha or Forest Dwellers who gave chosen members training in herbal lore (The Little People, Choctaw Legend, Zica'hot'a). The Maliseet called them, Geow-lud-mo-sis-eg, and depending upon one's attitude, the encounter with
alittle person could be beneficial or negative (Little People, Pat Paul). The Cherokee believed in three races: Stone People who could be malicious, Laurel People who were pranksters, and Dogwood People who were kind and helpful (Little People of the Cherokee, no author listed).
In Seminole lore, little people appear to those who were ill. The little people are believed to inhabit witches' brooms found on slash pines (Pinus elliottii Engelmann). Alice Micco Snow writes of the treatment to drive the little people away.

It is said there was a legend by the Shoshone Nation of Wyoming that there once existed a race of tiny people known as the Nimerigar.
The Shoshone said these little people would attack them with tiny bows and poisoned arrows. They said the Nimerigar killed their own kind with a blow to the head when they became too old or too ill to remain a useful part of their society.
It was a story reminiscent of the native legends of "little people" told all over the world. Other names for this tribe of people included geow-lud-mo-sis-eg, nunnehi, yunwi and tsunsdi. The discovery of the tiny mummy in the rock addadds some credence to the legend.
