le_aves's list "Names" of 3 great name ideas: Louisa - Elowen!

Names

Louisa, a quaint but strong vintage name, might feel fresher in English speaking countries than old favorite Louise, just as Diana and Julia have more energy than Diane and Julie at the moment. Part of this might just be that Louisa has never been so popular as Louise, so it makes a familiar but distinctive option alongside Eloise, Lucy, Luna, and Lucia.
 Very popular in the eighteenth century, Louisa was finally toppled at the end of the nineteenth by the French form Louise, which was a top name through the first quarter of the 20th century. Both derived from Ludwig, via Louis, the name has the powerful meaning "renowned warrior", making it a great contender for a spirited girl.
 
Familiar in France and the UK, Louisa re-entered the US Top 1000 in 2014 after a 45 year absence and a current year saw it rank in the latter end of the charts, given to around 380 babies. In comparison, Louise was given to more than 550 babies and ranked just outside the Top 500. 
 Louisa has many literary associations, including Louisa May Alcott, author of Little Women and Little Men; two Charles Dickens novels, Hard Times and Dombey & Sons; and two novels by Jane Austen, Pride and Prejudice and Persuasion. 
 Louisa is a First Lady name, being the wife of President John Quincy Adams. One of Meryl Streep's daughters is named Louisa.
 Some international variations: Luisa, Lovisa, Ludovica, and Luigia. Nicknames include Lou, Lu, Lulu, Ouida, and Ouisa.

Louisa

Familiar in the UK where it has featured just outside or towards the end of the Top 1000 since the late 90s, this spelling was once a well-used option in the US too, peaking in the 1920s and 30s, when it was in the Top 450. Now, it's making its way back to the American, mainstream, having re-entered the popularity charts in recent years.
 
While it is unlikely to reach the heights of popularity that sleeker Eloise has, it may well work it you're wanting to honor a Louise or a Louisa, or if you want to more easily access the unisex nickname Lou. This spelling was given to 266 girls in a recent year in the US, while Eloise was chosen for 3430.

Elouise

A beautiful modern Cornish nature name that is rapidly picking up steam in the States: even spawning variant spellings like Elowyn and Elowynn. In its native region, it wasn't widely used as a name before the twentieth century, when the Cornish language was revived. A fresh and magical member of the fashionable El- family of names, it has a pleasant, evocative sound.

The traditional Cornish pronunciation is with stress on the middle syllable: eh-LOW-en. But most English speakers seem to pronounce it with first-syllable stress, perhaps on the example of more familiar names like Eleanor and Elodie.

 
Elowen has been in the Top 1000 in the UK since 2017 and is the preferred spelling there, while in the US, Elowyn is the favorite, currently in the Top 500. Elowen is also gaining attention however, and entered the Top 1000 in 2024 when it was chosen for 294 babies.
