River

Nature names are big with parents, so it’s completely in keeping with this preference that River scores well in terms of chart favorites. A name like River—or Sky, Rainbow or Leaf—was once seen as odd or hippieish, but today it’s as acceptable as any traditional name. It comes from a Latin word, “ripa,” which translates to riverbank. Though more than twice as popular as a boys' name (Keri Russell of "The Americans" has a son, born in 2007, named River) it’s growing as a girls' name too.
