Eloise hit its peak rank in 2024 — meaning it is still climbing at the moment this article publishes. That's an unusual position for a name with medieval Latin roots and a 20th-century children's-book anchor. Most vintage revivals peak and then settle within a decade; Eloise has been climbing steadily since 2010 with no plateau yet visible.
The Plaza Hotel character versus the medieval scholar
Eloise has two distinct cultural anchors that contribute to its appeal in different proportions. The first is Eloise of the Plaza, the protagonist of Kay Thompson's 1955 children's book series illustrated by Hilary Knight. The character is precocious, mischievous, and lives in the Plaza Hotel; the book has stayed continuously in print for 70 years and shaped most American parents' first association with the name.
The second is the historical Héloïse d'Argenteuil (c. 1100-1164), the French abbess and scholar whose correspondence with Peter Abelard became one of the most famous love-letter cycles in medieval European literature. The historical Héloïse gives the name its intellectual register; the Plaza Eloise gives it the bright, playful one.
The French root and the spelling drift
Eloise traces to the Old French Héloïse, itself derived from the Germanic Helewidis (helan, "hidden" + wid, "wide"). The name became standardized in French ecclesiastical use through the medieval Héloïse and entered English in simplified spelling during the 19th century. The dropping of the diaeresis and the silent H is a typical Anglicization pattern that also affected names like Eleanor and Beatrice.
The name's recent climb has been helped by Penn Badgley and Domino Kirke naming their daughter Eloise in 2020, and by sustained high-celebrity placement in the 2010s (Kelly Cuoco's niece, several other entertainment-industry births). The cumulative effect is to mark Eloise as a current-cohort vintage choice rather than a museum-piece revival.
The still-climbing question
The counter-reading worth flagging: names that peak in the year of writing usually still have growth ahead, and Eloise's vintage-revival peers (Adelaide, Clara, Beatrice) are also showing late-stage climbs. Parents picking Eloise in 2025 should expect the name to feel slightly more common over the next decade — possibly settling around #40-50 — rather than retreating. That trajectory is a feature for parents who want a name that grows gracefully into ubiquity, but a small concern for parents specifically wanting distinctive.
Sibling pairings on naming forums lean into the soft-vintage cluster: Eloise and Charlotte, Eloise and Genevieve, Eloise and Beatrice. The nickname Lola is occasionally used, though most Eloises keep the full three syllables. Middle names tend short to balance: Eloise Rose, Eloise Mae, Eloise Grace, Eloise Jane.
