Here are some options, depending on the meaning you want to convey:
* "Anu" means "grace" or "favor" in Hawaiian. It could be a fitting alternative if Ann is a name that resonates with those qualities.
* "ʻĀne" means "elder sister" or "older sister". If Ann is older than you and you want to use a more traditional Hawaiian name, this could be a good option.
* "ʻAnela" is a variation of the English name "Angela" and means "messenger" or "angel." This could be a suitable alternative if you want a name similar to "Ann" but with a more Hawaiian feel.
Ultimately, the best way to find a Hawaiian name for "Ann" is to consider the meaning and sound of the name and choose one that resonates with you.
