Harriet has long been considered a stylish, upscale name in England, but it's still waiting to be revived in the US—though some parents seeking a solid, serious semi-classic are beginning to consider it.

Jackson is one of those names that's much more popular than you think, coming in near the top of our annual Playground Analysis, which ranks names by grouping all their spellings together. Last year, nearly 17,000 baby boys were named Jackson -- along Jaxon, Jaxson, Jaxxon, Jaxen, Jaxyn, Jaxsen, and Jaxsyn -- which counted together makes it the Number 3 boys' name.

Long common in Europe, the elegant and regal Juliana, also spelled with two n's, has invaded these shores, in tandem with the more classic Julia. Together with Julian, the name derives from Julius, a Roman family name. Its origin is shrouded in history, but possible roots include Latin iuvenis, meaning "youthfu"; Greek ioulos, meaning "downy-bearded"; or Jovis, a form of Jupiter, which means "sky father".

Light and glittery, but with plenty of spirit, Kinsley has risen quickly into the US Top 100. Balanced between preppy and cutesy, it feels like a fresh alternative to Kelly, Kaitlyn, or Kimberly.

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.

Leonard is the name of several saints, including one who is the patron saint of childhood, and another medieval saint who's the patron of prisoners--known for freeing prisoners he deemed worthy of God. Popular from 1900 to 1930, Leonard is perhaps more notable for those who dropped the name when they entered show biz than those who kept it: former Leonards include Roy Rogers and Tony Randall. Two musical Leonards did keep their names though--composer-conductor Leonard Bernstein and poet-singer Leonard Cohen. Leonard Woolf was the husband and publisher of great English novellist Virginia Woolf. These days, modern parents tend to prefer Leo or the romantic Italian Leonardo, especially since Leonard does not get pronounced with the trendy "Leo" sound.

Lincoln cracked the Top 50 for boys' names for the first time in 2016, more than 150 years after the death of its most famous bearer.

Latinizing Lawrence gives it a whole new lease on life. Like Leonardo, Lorenzo has been integrated into the American stockpot of names, partly via actor Lorenzo Lamas.

Malcolm is a warm and welcoming Scottish appellation (originally Mael-Colium) that fits into that golden circle of names that are distinctive but not at all odd. A royal name in Scotland, Malcolm is also a hero name for many via radical civil rights activist Malcolm X.

Marcella has been in mothballs for so long it's starting to feel stylish again. Depicted as the world's most beautiful woman in Don Quixote (where it's spelled Marcela), this long neglected name seemed dated for decades but just might be ready for restoration.

Tennis-related name popular throughout Europe that's never caught fire here.

Matilda is a sweet vintage name that has been gently climbing the popularity list for the past 15 years, after a half-century slumber. The spunky children's book heroine Matilda is one factor in its rise, along with others of its class like Eloise and Caspian.
