Best known as one of the moons of Jupiter, Callisto was a nymph coveted by Zeus who was turned into a bear by Hera, becoming the Great Bear (Ursa Major) constellation.

Callisto

Kallisto is a feminine name derived from ancient Greek mythology. It originates from the Greek word "kallistos," meaning "most beautiful." In mythology, Kallisto was a nymph who was transformed into a bear by the goddess Hera and later placed among the stars as the constellation Ursa Major. This alternate spelling of the more common Callisto adds a distinctive visual element while maintaining the mythological connection. The name has seen very limited use, making it an unusual and exotic choice. It carries connotations of celestial beauty and cosmic significance, particularly with Jupiter's moon Callisto named after the same mythological figure. Parents attracted to names with classical origins and astronomical associations might find Kallisto especially appealing.

While it may look like a variation of popular Leo, Llio is in fact a Welsh name, derived from Gwenllian, the medieval name of a legendary princess who is a national heroine in Wales. Given to a small handful of girls most years in Wales — three in a recent count — the double L sound is hard to translate into English because it is specifically Welsh. 
 
A rough guide to the pronunciation however would be SHEE-aw, the double L being somewhere between the L in please and the sh sound. As such, you might see it described as HLEE-aw too, HL- being a frictive sound.

A peppy nickname name associated with Lolo (born Lori) Jones, American track and field champ.
