Newly fashioned but familiar and with an on-trend, unisex feel, Addison seems like the perfect solution for anyone who can't decide between Madison, Adeline, and Alison.

This rhythmic last-name-first-name projects the creativity and inventiveness of Thomas Edison. It's an English surname deriving from either Adam or Eda, a medieval diminutive of Edith.

Despite its origin as a patronymic meaning "son of Adam", Addison really caught on for baby girls in the US around the turn of the millennium, following in Madison's footsteps to peak at #11 in 2007 and again in 2010.

Scottish names that started as surnames are a class unto themselves. This old Scottish surname name debuted on the US Top 1000 in 2016 -- bolstered, no doubt, by the extreme popularity of Easton, just one letter away.

Variation of the very trendy Addison, perhaps lending itself more obviously to the nickname Addy.

Abstract painter Ad Reinhardt, né Adolph, gave his short name a lot of artistic cred, but it remained securely a nickname. The extra "d" in this version helps it stand on its own, for better or worse.

Same problem as Eóin -- squared.

Uruguayan footballer Edinson Cavani gave his unique first name a boost following the 2022 World Cup.

As soon as a name becomes mega-popular, parents start to look for spelling variations to set their child apart. This is one of the less graceful ones.
