The name Arya is a boy's name meaning "noble". Arya and is often added to user-created lists like First and middle ideas for sibling to Lake and discussed in our forums with posts like "Names on NB that make you go WOW!".
From the experts:
A venerable boys' name in Persian and South Asian cultures that is increasingly used for girls in most parts of the world, thanks largely to the popularity of Game of Thrones character Arya Stark. In the U.S., for instance, there were 1890 newborn girls named Arya in 2016 and just 54 boys in 2016. The related Aryan remains mostly male, however, so it would likely be a better choice for a little boy, if you don't mind the other meaning.
