Felix is one of those ancient but nontraditional names for boys that have come into favor over the past few decades, a favorite of parents who want a masculine name with history and heft that breaks ranks with the standard Franks and Freds. Felix is also an international darling, ranking in the Top 100 in several European and English-speaking countries.

Sleek and stylish with a touch of quirkiness about it too, Maxine is a popular choice in Belgium and France, and has been climbing up the US charts too. Following a two decade absence, it re-entered the Top 1000 in 2016 and a recent year saw it rank just outside the Top 500.

Beatrix has a solid history of its own apart from Beatrice, with that final x adding a playful, animated note to the name's imposing history and stately vibe.

The name of a Christian saint and a city in Ohio, Xenia is one of the more accessible and intriguing x names. It is the name of one of the Bond Girls--played by Famke Janssen in the film "GoldenEye."

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.
