Names of characters from books I have read

The mythological Morrigan was the ancient goddess of war, often symbolized by a crow. Besides being a name, this is also used as a proper noun preceded by an article: the Morrigan, defined as a monster in female form. The meaning of Morrigan has been related to both terror and greatness. While some relate the name to Morgan of the Arthurian legends, Morrigan and Morgan are actually unrelated.

Nadia, an accessible Slavic favorite, has a strong run of popularity in the US in the early 2000s, partially thanks to the character on Lost called Nadia but actually named Noor, but it's since slumped down the rankings. An earlier inspiration was Romanian gymnast Nadia Comaneci, who won the 1976 Olympics.

Naomi was once a primarily Jewish name from the Old Testament that referenced the mother-in-law of Ruth. Because of this, it is a symbolic name given to girls on Shavuot when the story of Ruth is read in the synagogue.

This is the most popular Welsh form of Agnes. Variants include Annest and Nest. There was an eleventh century Nest who was known as 'Helen of Wales' for her beauty and the problems it caused.

Russian forms, like Russian supermodels, are hot these days. This is a strong, worldly way to make Nicholas new; it was chosen for his son by Barry Bonds, Jr. Nikolai also comes with several attractive nickname options, including approachable Nik, spunky Niko, or even hip Kai. A traditional nickname for Nikolai in Russia is Kolya.

Nina is as multiethnic as you can get: Nina is a common nickname name in Spain and Russia, a Babylonian goddess of the oceans, and an Incan goddess of fire. Here and now, it's a stylish possibility that's been underused. "Weird Al" Yankovic chose this decidedly nonweird name for his daughter.

Noah is nearly a patriarch of popular baby names at this point, going from Old Testament graybeard to Top 10 name in 2009, hitting Number 1 in 2013, and now settled into second place in the US for the past seven years.

Nova has the feel of both newness, from its meaning, and great energy as an astronomical term for a star that increases suddenly in brightness before fading.

Officially a shortening of the traditional and tricky Gaelic Fionnghuala/Fionnuala, Nuala makes a lovely choice all on its own. Nuala is well-used in Ireland.

Oscar is one of the most stylish Old Man Names of our era. While it's softened slightly in popularity over the past 20 years, that may be considered a very good thing.

Philippa is a prime example of a boy's name adapted for girls that was common as crumpets in Cornwall, but rarely heard stateside. That was before the advent of royal sister-in-law Philippa Middleton, who goes by the lively nickname Pippa.

Castor's twin in the constellation Gemini. That final x makes this name modern and cool.
