Aria is a multi-cultural name with two extremely popular versions: this more word-like one along with Arya, the spelling used for the feisty young heroine of Game of Thrones. There were about 6400 baby girls named Aria in the US last year alog with 2400 named Arya, which counted together places the name in the Top 10.
 
The light and airy Aria entered the list in 2000 and now ranks among the Top 25 girl names in the US. In Italian, Aria's literal meaning is air, while in Hebrew it's a form of Ari meaning lion. An Aria is a musical term denoting a kind of song or melody, often in an opera.
Aria is a Top 100 name throughout the English-speaking world and also ranks highly in France and several European countries -- though notably not in Italy or Israel. In Persian, Aria is a male name, and in Indian it is considered unisex. 
Aria is also an improbably cool saint's name. Saint Aria (or Arria) of Rome was an early Christian martyr.

Alianne

A light and pretty pan-cultural name which can be considered a variant of either the Greek name Selene or Selena, meaning "moon", or of the French Celine, meaning "heavenly". An attractive choice that is surprisingly rare in the US: out of the Top 1000 since 2006.

Daenerys is yet another girls' name invented by "Game of Thrones" author George R. R. Martin that is beginning to gain some traction in real life. Daenerys was used for 67 baby girls in 2013 while one of the character's titles, Khaleesi, was given to 241 baby girls. And the name Arya, also from the hyper-popular series, is one of the fastest growing <a href="https://nameberry.com/girls-names">girls' names</a> in the country.

Marella is an Italian name that feels at once unique and familiar, which may either be the best or worst of both worlds, depending on your preference.

Only a few dozen baby girls were named Marella or Marilla in the most recent year counted in the US, so this could make an unusual honor name for grandma Mary or Maria.

Nerilka

Game of Thrones author George R. R. Martin is a master namer, and this unusual choice from India is beginning to be heard in nurseries as well as on television.  Sansa was perhaps slower to catch on than other names such as Arya and Khaleesi as Sansa Stark was in the first seasons of the show a weak and compromised character. But she's developed a good measure of backbone and integrity, which makes her lovely name a more attractive possibility.  In 2015, 20 baby girls in the US were named Sansa, a number we expect to rise.
