ErrantNauta's list "Earthy" of 3 great name ideas: Eos - Hanalei!

Earthy

Eos -- that's pronounced with a short e like eros without the r -- is the Greek Titan of the dawn. Any ancient name with a sleek modern feel has definite revival possibilities. Eos could be an inventive way to honor grandma Dawn. 
 
Eos is also a Welsh bird name that is occasionally given to girls in Wales — pleasingly the nightingale, so this name covers both morning and night.

The Calytrix flower is endemic to much of Australia and is part of the myrtle family. They are commonly known as star flowers, due to their dainty (usually bright white) 5 petalled flowers. The name derives from Greek calyx "cup" + trix "hair".

Calytrix

An appealing Hawaiian name which belongs to a town, river and bay on Kauaʻi island in Hawaii. The two possible meanings of the name, "crescent bay" or "garland (lei) valley" both describe the beauty of the place.
 
Hanalei is a unisex name which is sometimes used for boys as a Hawaiian version of Henry, although the names are not etymologically related.
