A royal name in ancient Egypt that's never quite made it to the modern world, though nickname Cleo is widely used. Other now-extinct Cleopatra diminutives, including Cleora and Cleola, achieved some popularity in the early 20th century when there was a crazy for all things Egypt-related as the ancient tombs were opened and artifacts displayed. In the US, Cleopatra became a popular silent film in 1917 starring Theda Bara.

Charity is one of the Big Three abstract virtue names, along with Hope and Faith, though far less widely used than the others.

A name with a weather-related meaning, a tie to mythology, and an airy, bright sound, Aella is a quietly rising choice, with 51 American babies receiving the name in a recent year.

Gerard is currently in style limbo, after reaching peak popularity in the 1950s. With its strong meaning and gentle sound, it may be back in a generation or two. But for now, a boy called Gerard will likely be the only one in his class...unless you live in Catalonia, where it was recently in the Top 10.

Hildegard is an ancient name that sounds it, but it does have sweet short forms Hildie and Hilda to recommend it, as well as several illustrious historical bearers.

Theodoric feels prehistoric, though with short form Theo one of the hottest names around, this old German names for boys may soon feel new again.

Dropping the final "k" of Frederick definitely makes it a more user-friendly classic boys' name. It streamlines it and also hints at Frederic's status as a French variation of the Germanic Frederick. Either way, this is a strong classic to consider if you're not afraid of a little dusty residue.

Justina was the pre-Justine feminization of Justin, now a possible alternative to Christina. Oddly, while Justine feels like a name unto itself, Justina feels like a pinned-together feminization in the mold of Richarda or Benjamina. Still, it may appeal as one of the unusual-yet-familiar girl names starting with J.

A very Christmas-y Christmas baby name, that may avoid the Santa image by instead adopting the alternative spelling Klaus.

An ancient Roman clan name, Flavia is one choice that's unusual but historic. Now a Top 60 name in Italy, Flavia has been a rarity in the US, but with the upswing in F names for girls, this could change. Seen more in literature than real life, Flavia was used as far back as an1580 romance, then in a William Dean Howells novel and as a Princess in The Prisoner of Zenda. Although the original pronunciation is FLAH-via, Flavie (as in flavor) could make a cute nickname.
