Native Americans from Ohio refuse to go on to Washington (6)
I believe the answer is:
ojibwa
'native americans' is the definition.
'ohio refuse to go on to washington' is the wordplay.
'ohio' becomes 'o'.
'refuse' becomes 'jib'.
'to go on' says to put letters next to each other (in a down clue, some letters go on top of others).
'to washington' becomes 'wa'.
'o'+'jib'+'wa'='OJIBWA'
'from' is the link.
(Other definitions for ojibwa that I've seen before include "Algonquian people" , "Native American" .)
