Not to sound snarky or anything, but there are literally hundreds of Native American languages. Saying a name means such and such in "Native American" is like saying a name means such and such in "European".
Aside from that little rant, I'm afraid I can't be much more help, because Donakya doesn't ring any bells for me. Sorry!
