Like Horace, Horatio is a variation on the Latin Horatius, but its Shakespearean and optimistic Horatio Alger pedigree makes it an attractive up-and-comer, especially with its cool final o. A modern reference is the charismatic TV character Horatio Caine played by David Caruso in CSI: Miami.

Phyllis has been used by classical poets for the idealized pastoral maiden. A Greek mythological name of a woman who was turned into an almond tree, Phyllis was in the Top 100 from 1916 to 1958, reaching #24 in 1929, and has the (remote) possibility of joining other revived s-ending names like Iris. In the 'St Clare' book series by Enid Blyton Phyllis is nicknamed Fizz. Just a thought. Phyllida is a variation that sounds at once more old-fashioned and more stylish.

Before there was Aspen, Denver was the Colorado city name of choice, and it reentered the US Top 1000 in 2015 after a 14 year absence as a stylish two-syllable boys’ name with its trendy -er ending. Its decade of greatest use was the 1920s, when it reached as high as Number 422.

Emerald is the intriguing color and jewel name of the deep green stone treasured as far back as ancient Egypt — it's supposed to open one's heart to wisdom and to love and be good for strengthening relationships — which could make for an interesting, unusual name, particularly with the popularity of so many Em-starting names.

This Nova-offshoot is hot in the Netherlands, where it was recently one of the fastest-rising names of the year. It could eventually see great success in the US as well, and was given to 46 American girls at last count.

The name of the wife of Alexander the Great, more attractive than the better-known Roxanne. Roxana was first used in the English-speaking world in the 1600s and was popularized by Daniel Defoe's novel Roxana, published in 1724. An underused and attractive possibility and perfect if you're searching for names that mean new beginnings.

With diverse roots and meanings, Ayana is a cross-cultural possibility with Arabic, African, and Kazakh origin.

It appeared in the Kazakhstani top 15 multiple times in the 2010s and recently ranked in the UK Top 500.

A fairly common Greek name that would fit in well here.
