Heidi became known—and popular—via the 1880 eponymous children's classic by Swiss writer Johanna Spyri and, despite decades of American Heidis of all sizes, shapes, and personalities, the name seems permanently tethered to that spunky little girl on the Alpine mountaintop in the book and Shirley Temple movie.

Henry is back. The classic Henry climbed back onto the Top 10 in the US in 2021 for the first time in over a century, and now stands at Number 7.

A name that sounds so old-fashioned some parents out there might conceivably find it quirky enough for a comeback, along with other one-time fuddie-duddies like Oscar and Homer.

In the Bible, Jairus was the father of a girl resurrected by Jesus. Though it is the original, its variation Jairo is more popular.

Jarvis, one of the original two-syllable nouveau boys' choices, is a saint's name with a certain retro charm and a nice quirky feel. Though Jarvis peaked in the late 1880s, he is beginning to sound fresh again.

The Jodie spelling might be even more obscure, at this point, than the fading original, except actresses Jodie Foster and Jodie Sweetin have kept it in the public eye.

Jonas has a slightly more grandfatherly image than the English version of his name, but that only adds to its retro appeal. And though it may lag behind Jonah in this country, Jonas is riding a huge wave of popularity in Europe, where it ranks highly in Germany, Switzerland, Austria and Norway.

Judy was the nickname of choice for almost all the Judiths born in the 1940s and 50s; today's little Judiths are much more likely to be called Judith -- or, possibly, Jude.

Your friendly next-door neighbor...not your baby. Although Larry was once one of the most popular boys' names starting with L, that title now belongs to Liam.

Laura is a hauntingly evocative perennial, never trendy, never dated, feminine without being fussy, with literary links stretching back to Dante. All this makes Laura a more solid choice than any of its more decorative counterparts and one of the most classic girl names starting with L.

This pet form of Helena and other ena-ending names, long used as an independent name, is attracting notice again as an option both multicultural and simple. Lena was a Top 100 name from 1880 to 1920.

Like Lottie, Letty is a nickname name not heard in over a century, giving it the patina of a treasured antique.

Levi, lighter and more energetic than most biblical names, with its up vowel ending, combines Old Testament gravitas with the casual flair associated with Levi Strauss jeans.

Lewis is the best spelling to choose if you want this pronounced with the S. Lewis has been in the Top 5 in Scotland since 2000, and is one that parents in the U.S. are just beginning to rethink.

Lilah may be a simple spelling variation of Lila—or you might think of it as a shortening of Delilah or an Anglicization of the Hebrew Lilach, which means lilac. Whatever the root, it's a beautiful and stylish name. The final h adds balance or creates needless complications, depending on your viewpoint.

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.
