Apaches - Yuma or Yulkepai
One of the divisions of the Apache nation. "Until 1904 there lived with the Apaches of Arizona a number of Indians of Yuman stock, particularly Mohave-Apaches or Yavapai but these are now mostly established at old Camp McDowell." Hodge.
Farish says: ""The word Yuma probably means "spotted belly sparrows." He fails to say where he got the idea.
