Name pronunciation

My daughters name will be Aubrynn Mae. Aubrey was my grand ma's name and Lynn is my moms middle name. It's pronounced Awe-brynn. No one can pronounce it! I tell them to just call her Aubrey or Mae but Aubrynn will be her name and his grandmother said if we aren't going to call her by her name we need to change it and she thinks Aubrynn is a waste of letters anyways. She's pissed that we aren't naming her Sandra Sou after her.
