Hmmm, how do you pronounce it, Zen - Zel or Zen-Zel -eh
Either way, it's pretty on paper, but not nice sounding in my opinion. As for
Amina, I think its beautiful for any ethnicity.
I wouldn't get too hung up on the ethnic thing. Like I've before I've known people with names from a different culture that their own, and it hasn't caused them any bad consequences, other than the "how do you spell that??"
