elisep's list "Nature Names" of 2 great name ideas: Shadow - Sugar!

Nature Names

A daring word name with a touch of mystique, Shadow is an edgy choice for a baby that some may say is best reserved for pets. Nevertheless, it has been appearing in the US stats for girls since 1974 and for boys since 1987.
 
It was at its peak in 1993, when 22 girls and 36 boys recieved the name, (possibly thanks to the release of the Honda Dodge Shadow range or the apperance of Shadow, the golden retriever in Disney's 1993 Homeward Bound: The Incredible Journey). In a more recent year, it was chosen for 6 girls and 14 boys in the US.
 
Borne by characters in the show and book American Gods and in the game franchise Sonic the Hedgehog, it has similar vibes to Raven, Moon, and Jinx, and similar sounds to Shiloh, Marlow, Shay, and Shannon.

Shadow

You can call your daughter Sugar, but it's probably best to keep it as a term of endearment. For sweet names, you try Dulcie, Honey, Mitsu, Amai, Sherine, Melita, Eulalia, or Melina, but Sugar does work as a generic nickname.
 
A handful of babies have been registered as 'Sugar' over the years.
