From the experts:
Reign is one of a new, ahem, kingdom of word names that suggest a high-born child, joining Royal, Lorde, Titan, Saint, King, Princess, and Noble. We predicted this kind of defining name to be the Number 1 baby name trend of 2015...two weeks before Kourtney Kardashian and Scott Disick named their third child, a boy, Reign. Reign is as appropriate for girls as for boys. The female version is often spelled Rain -- or Raine or Rayne -- though that makes is more nature and less royal word name. Reign entered the US Top 1000 for the first time in 2016.
