It's another "no" to Destiny, I think Ebony is nice, classier than Destiny. I can see it working in many different jobs/life stages- you dont get the same preconceived ideas about who Ebony is compared to Destiny.
Faith is pretty and classic, sounds very strong and not "cutesy girl" - woman called Faith aren't for fucking about with.
I don't know if this is something you'd want to factor in, but as a white woman, if I heard the names Destiny or Ebony, I would be expecting both to be woman of colour. I wouldn't assume a race for Faith (although assume Christian parents).
