I actually don't mind this name at all, never have. I think it's the meaning that gets me! That said, I do prefer it for a mn. Unfortunately it wouldn't work with my ln, as that starts with a W.
What about these combos:
Amy Winona - "Beloved first-born daughter".
Love this combo!
Belle Winona - "Beautiful first-born daughter".
