How would you pronounce this and Name drama?!

How Would you guys pronounce the name Mackenzie? I named my daughter Mackenzie-Ray and my dad has always been against her name since day one when he met her in the hospital.. Saying that I should drop the Ray at the end (she gets that from My aunt whose like a second mom to me) and now that he's found out How it's SPELLED he's taken to pronouncing it wrong AND dropping the Ray at the end off when he KNOWS how to spell it...
