Geronimo, for one (6)
I believe the answer is:
apache
'geronimo for one' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for apache that I've seen before include "Fierce Indian of American SW, or Paris ruffian" , "US native" , "Native American - French hoodlum" , "Parisian ruffian - Indian" , "Geronimo's people" .)
