Where I come from, most Muslim girls bear this in their name. For instance, you have such combinations as Nur Shakila, Nur Iman, etc. However, their bearers go by the second name, and not "Nur" (for the examples above, they'd go by Shakila and Iman respectively). I wonder why, sometimes.
Another spelling is Nour (noor). I also know a little girl, whose family is from Egypt, named Nouran (noor-ahn; roll the r a little as you say it). It means "light of the Quran" in Arabic.
