One young woman wrote this about choosing her Hebrew name:
I started day-dreaming about what Hebrew name I would pick from the very beginning. Choosing your name is an opportunity to choose your identity... and I wanted my identity to be sassy and awesome, meaningful and intelligent, and infinitely cooler than I actually am. And then finally, after two years, I settled on the perfect name: my legal one. The name that my mother and father chose for me. Because becoming Jewish, for me, was an act of choosing to recognize *who I already am.* I will always be my parents' daughter - a reality that I honored and recognized by keeping my legal first name as my Hebrew name. And just as I have now chosen a future among the Jewish tribe, I added "bat Avraham v' Sara" to my legal first name. My Hebrew name = my family of origin + my family by choice = my past + my future. My Hebrew name doesn't aspire to a new identity; instead, it does no more and no less than recognize me for who I am.
My Mom cried when I told her. There had been serious potential for her to feel alienated by my conversion (though we were both trying hard to prevent that), but my choice of Hebrew name made her feel included, validated, and honored. It really helped to make my conversion a beautiful experience for everyone.
(Granted: I'm really really lucky to have a legal name that is a diminutive of a classic biblical name!)
Nina found her name on Kveller's Jewish Baby Names List. Maybe yours is there!
