From the experts:
Saint as a descriptive word name was first chosen by rocker Pete Wentz for his younger son (baby brother is Bronx), and now Kim Kardashian and Kanye West have catapulted the name into the celebrity stratosphere by choosing it for their baby boy. The couple called their baby "Saint" throughout the pregnancy because his conception had been so difficult. Saint was named in our predictions for the top baby name trends of 2015, on descriptive word names which also include Royal and Noble, King and Rogue. Saint is moving beyond the group of names that are only celebrity baby names and into the general lexicon.
