The lovely Lorelei, a name from old German legend, was a beautiful Rhine River seductress whose haunting voice led sailors to hazardous rocks that would cause them to be shipwrecked. And this siren image clung to the name for ages.

Lysander is a distinctive Greek name that could be thought of as a more creative cousin of Alexander. In ancient history, Lysander was the name of an esteemed Spartan naval commander and his literary cred comes from one of the two star-struck young men in Shakespeare's A Midsummer Night's Dream, as well as one of the twin sons (the other being Lorcan) of Luna Lovegood, whom we learn about in the Harry Potter epilogue.

Lilith is derived from the Akkadian word lilitu meaning "of the night." In Jewish folklore she is portrayed as Adam's rejected first wife, who was turned into a night demon for refusing to obey him. Lilith is unrelated to most other Lil- names, with the exception of Lilita, which is the Latvian variation.

Strong but sweet, Leah is a classic name that doesn't feel dull or dusty. It's got plenty of dignity, grace, and pluck, making it a solid choice in the 21st century.

Lavinia is a charmingly prim and proper Victorian-sounding name which actually dates back to classical mythology, where it was the name of the wife of the Trojan hero Aeneas, who was considered the mother of the Roman people.

Can Linus lose its metaphorical security blanket and move from the Peanuts page onto the birth certificate? We think it has enough charm and other positive elements going for it for the answer to be yes.

A strong, grounded choice that still has plenty of energy and charm, Leona is the feminine form of Leon, itself derived from the Greek word for "lion". Associated with courage, leadership, and royalty — and the star sign of July and August — Leona is popular in Croatia and Sweden, but familiar across the US, the UK, and continental Europe.

Could Lowen be the next Owen, Rowen, and Cohen? This Cornish name certainly has the right sounds to be an American hit, and is rising dramatically for both boys and girls.

Linnea is an attractive Scandinavian name that derives from the renowned 18th century Swedish botanist Carl Linnaeus, who developed the Linnean system of classifying plants and animals.

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. This is especially remarkable because, as crazy as it seems now, Lincoln was deeply out of fashion as recently as the late 90s, consistently hovering near the bottom of the Top 1000.

Lumi may be a rare girls' name in the USA and England, but it comes in the Top 50 in Finland, where it means snow. Given the popularity of Winter, Holly, Ivy and many other wintery-christmassy names, we think that short and spunky Lumi definitely has potential for greater usage outside its home country as one of the more unusual names for Christmas babies.

Leif is one of the most recognizable Scandinavian names, thanks to Icelandic explorer Leif Erikson, and is still one of the best, with a pleasant aural association with the word leaf.

Lula has a firecracker personality, a singing and dancing extrovert. Interesting that Lulu was a Top 100 name when the Social Security list was born in 1880, but it's been sliding ever since and has not been in the Top 1000 for decades. Modern parents in love with Lulu might well reverse that trend.

Popular in the first half of the 20th century, Leland briefly fell out of favor in the late 90s. After a short break from the US charts, it returned in the mid-2000s, with actor Brendan Fraser choosing it for his youngest son, possibly making it feel cool again. Given to around 500 boys each year, Leland is in the Top 600.

Leonie is a chic French and German form of a name that exists in a range of variations from Leona to Leonia to Leon to Leo to Lionel, all newly fashionable after a couple of generations in style limbo.

Lionel is one leonine name that hasn't taken off as cousins Leo and Leonardo have, though it did reenter the Top 1000 in 2010 after several years away; it was at its highest point in the 1920s and 1930s.

An up-and-coming nickname-style name, hugely popular in Germany and on the rise in the UK, Leni is stylish but sweet. Chosen for her daughter by high-profile German supermodel Heidi Klum back in 2004, Leni with its concise spelling and European feel is also on the rise in the US, alongside Lennie, Lenny, Lennox, and Lennon.

A growing number of high-profile (and other) parents are choosing to honor their musical idols, such as Hendrix, Presley, Jagger, and now Lennon, an Irish name for girls as well as boys with a wonderful meaning on many levels. Lennon first came to notice when Liam Gallagher and Patsy Kensit used it for their son in 1999, and singer-musician Adam Pascal followed their lead two years later.

Its mellifluous sound makes Leonora--which has a rich history and a tie to the popular Leo names-- a keen possibility for revival. Though it's been hiding below the Top 1000 since the 1940s, Leonora is being rediscovered by stylish parents in the US and Europe.

This concise one-syllable name, has two possible derivations and two positive meanings associated with it. In Hebrew, it means "heart", while in Russian it means "lion". So strong and simple Lev has both a soft and a fierce side.
