Aiden in all its spelling variations is the Anglicized version of the Irish Aodhán, which was originally a pet form of the Irish name Aodh (pronounced 'ee'), who was the old Celtic god of the sun and fire. St. Aidan was a famous seventh century Irish saint, noted for his kindness and generosity and for spreading Christianity.

Hayden – a formerly obscure name that's risen to huge popularity – has dipped in this year's ratings. Though Hayden is among the most distinctive of the bunch, it gets lost in the crowd of Jaidens, Bradens, Aidans, and endless variations. Associated with Hayden Christensen, of Star Wars fame.

Aidan was originally a pet form of the Irish name Aodh (pronounced 'ee'), the name of the old Celtic god of the sun and fire. The name was borne by numerous early Irish saints, one of whom was noted for his kindness and generosity.

Caden is a key member of the rhyming contingent that includes Aiden, Jayden, Kayden, Brayden et al. It may derive from the Celtic Cadan or Irish Cathán, both from the same root meaning "battle". It is also possible it comes from Cade, meaning "round" or "barrel".

Reminiscent of 70’s favorite Jason, and sharing sounds with the perpetually popular James, Jayden is one of the more enduring members of the -ayden trend.

A popular member of the -ayden family, Kaden ranks alongside Kaiden, Kayden, Kasen, Kade, Caiden, Cade, and Caden in the US Top 1000. A 90s invention that took off in the 2000s, Kaden is concise and modern, with its popular K initial.

Brayden is the top spelling of one of the epidemically popular rhyming cousins of Aiden, hitting the Top 100 in 2005.. It has dipped a bit recently, but is still widely used. Other popular spellings include Braden, Braeden, Braydon, Braiden, Braedon and Bradyn. Take your pick.

A newly successful name for girls, which, like Brayden and Caden, used to be strictly for the boys. Young Heroes and now Nashville star Hayden Panettiere planted it in the girls' camp.

This version of Kaden is also a popular choice and one of the many boys' names starting with k that can also start with a C, as in Caiden, Cayden et al.. Kaiden Alenko is a character in the video game Mass Effect.

This member of the aden/ayden extended family is a popular choice not only in the US but across the pond in England, Wales and Scotland as well. Angie Everhart has a son named Kayden Bobby.

Cayden is one of the many spellings of this popular name, made all the more popular when they're counted together. According to our annual playground analysis, sound-wise at least, Cayden is the 13th most popular name in the US, given to more than 10,600 baby boys.

Kade falls into the trend of using a letter K at the beginning of a traditionally C-starting name, perhaps to give it a sharper edge. Trending since the 90s, Kade is currently in the Top 400, while Cade ranks nearly around 70 places ahead. Given to 933 babies in 2023, it is a consistently used name.

While Jadon is the authentic biblical name, Jaden is by far the more popular spelling, first noticed when Will and Jada Pinkett Smith used it for their now grown (and famous) son. It has since swept the country for both sexes, with a wide variety of spellings and rhyming cousins.

Aidan in all its many splendored varieties, particularly Aiden, had a spectacular rise up the list, and the phonetic Ayden came along for the ride. It is also used in Turkey.

This once obscure name was propelled to fame by Britney Spears, and by Will and Jada Pinkett Smith in the 2000's. It skyrocketed into the US Top 10 for boys, but it also saw significant use for girls.

Caedmon is a masculine name of Anglo-Saxon origin with deep historical roots. It gained prominence through Caedmon, a 7th-century English poet considered the earliest known English poet whose name is recorded. According to the Venerable Bede's historical accounts, Caedmon was an illiterate herdsman who received divine inspiration to compose religious poetry. The name likely derives from Celtic elements meaning "wise warrior" or "battle wisdom." Though rare in modern usage, Caedmon has seen modest revival among parents seeking unique names with historical significance. It appeals to those drawn to medieval English heritage, literature, and names with scholarly associations. The name carries connotations of creativity, wisdom, and inspired eloquence.

One of the trendiest of the new two-syllable boys’ names that have swept the country in the past few years, including the rhyming Aidan, Caden, Kaden, and Jaden. It's been falling on the US Top 1000 lately but it is still among the most popular contemporary English names for boys..

Jaiden could be a variation of the Hebrew name Jadon, meaning "thankful", however, it may also be a modern invention, taking inspiration from Hayden and Aiden and combining it with the popular J- sound of James, Jason, and Jacob. While it has declined in use in the US in recent years, and is less popular than Jayden or Jaden, when combined with all its other spelling variations, it will still feel like a Top 50 name.

Aedin is a masculine name with Gaelic origins, serving as a variant spelling of the Irish name Aodán (or Aidan). Derived from the Old Irish element 'aed' meaning 'fire,' it carries connotations of passion, brightness, and warmth. The name has ancient roots in Irish mythology and history, with several early Irish saints bearing variations of this name, most notably St. Aidan of Lindisfarne who spread Christianity in northern England during the 7th century. While the spelling Aedin is less common than Aidan or Aiden, it offers a more distinctive appearance while maintaining the authentic pronunciation. This variant has gained some modest attention in recent decades among parents seeking names with Celtic heritage that balance traditional roots with a contemporary feel.

This play on Hayden is likely influenced by the popularity of the Aiden names. It has appeared in the US Top 1000 for eight of the past twelve years.
