Geronimo's people (6)
I believe the answer is:
apache
'geronimo's people' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for apache that I've seen before include "settler in Oklahoma?" , "A native N. American people" , "Parisian ruffian - Indian" , "Geronimo was one" , "N. American native; French ruffian" .)
