For all the people complaining about the pronunciation, deal with it. If you can pronounce Mhackenzeigh Graeighcynne, you can pronounce Potsʉnakwahipʉ.
HOW do you even pronounce this? If you name your child this or this is your name you will be the very last one to write your name in class, for the fifth time the teacher says " Are you done writing your name yet?" Student "No" Ten minutes later... Teacher: "Are you done, for the sixteenth time?" Student "NO TEACHER! MY NAME IS SO LONG I WANT TO CHANGE IT" Twenty minutes later... Teacher: "Are you done yet? This is the twenty seventh time!" Student "YES! FINALLY!" Too long and complicated, how is this even a name?
