Sky may be a bit hippieish, but it's bright and sunny nonetheless. Sky joined the Top 1,000 baby names in the late nineties and early 2000s but is off the radar again now. Sky was the choice of magician David Copperfield for his daughter, born in 2010.
Sky is an ambigender nature name that was first legitimized as the character of Sky Masterson in the 1950 musical Guys and Dolls, played in the film version by Marlon Brando. It's a name we appreciate for its clear, wide-open feel, less hippyish than others like Rainbow and Starlight, and makes an appealing middle name possibility.
