Allison peaked in 1994 at rank 31 and is currently at #99. The 30-year descent from the early-90s peak has been gradual and is showing signs of leveling off. The total count of more than 316,000 American Allisons makes the name one of the most numerous current top-100 picks by historical depth, even though its peak has clearly passed.
The Germanic root and the spelling proliferation
Allison derives from the Germanic Adalheidis (the same root that gives Adelaide and Adeline) via the Old French diminutive Aalis, ultimately producing both Alice and Allison through different pathways. The Norman French Aliçon was the diminutive form that Anglicized into Allison and similar variants. The medieval English use was mixed-gender for several centuries before settling into primarily female use through the 19th century.
The current SSA tracks at least four major spellings as separate entries: Allison, Alison, Allyson, and Alyson. Allison is the dominant American form, with the alternatives trailing significantly. The cumulative count across all spellings places the name family meaningfully higher than any individual rank suggests.
The Allison surname pathway
An alternate origin treats Allison as a surname meaning "son of Alice," derived from the same medieval Aalis root but through different morphological pathways. The surname is Scottish and Northern English in primary use, with various Allisons appearing in 16th-19th century records as a family name.
The first-name use as a girls' name accelerated in the 1980s alongside the broader American interest in surname-feel girls' names. The 1985 film The Breakfast Club featured Ally Sheedy as Allison Reynolds, giving the name a teen-movie cultural anchor during its strongest growth period.
The post-peak settling pattern
The counter-reading worth flagging: Allison's descent from #31 in 1994 to #99 today follows the typical post-peak settling for names that crested with a specific cohort. The 1990s Allison generation is now in their late 20s and 30s — past prime parenting age for first children — and the name's appeal hasn't translated cleanly to subsequent generations. Parents picking Allison in 2025 are increasingly choosing it for its established feel rather than its trendiness.
The name's cross-cultural readability is moderate. Allison works in English-speaking contexts but is less common in non-English European traditions, where Alice and similar forms dominate. The Y-spelling Allyson tends to read as more American and slightly more contemporary, though the I-spelling Allison remains dominant.
Sibling pairings on naming forums lean toward 1990s-classic picks: Allison and Elizabeth, Allison and Lauren, Allison and Natalie, Allison and Rachel. Middle names tend classic: Allison Rose, Allison Grace, Allison Marie, Allison Elizabeth.
