Cool and Semi-Unusual Names Starting with A

Aeryn

Best known as the princess of the Elves in Tolkien's Lord of the Rings, Arwen is a fantasy-inspired choice that feels perfectly down to earth. In 2022, it entered the UK Top 400, making it one of the fastest rising names, more than doubling in use from the previous year.
 
For many of his character names, Tolkien took inspiration for Welsh, and Arwen and its masculine counterpart Arwyn do have some history of use as legitimate Welsh names, possibly influenced by the ancient Welsh Arianwen. In this case, the name would mean "fair, blessed", while in Tolkien's world, it has a more regal air. 
 
Similar in sound to Elowen, Gwen, Aria, and Ariana, Arwen has seen steadily increasing use in the US since the early 2000s. Currently given to around 180 babies each year, actress Caterina Scorsone and musician Rob Giles chose the name for their daughter in 2019. 
 
Like with any pop culture inspired name, you would have to decide if you'd mind people asking or assuming you were big Lord of the Rings fans, but with its grounded and familiar sounds, Arwen may continue to rise in coming years.
 A trivia tidbit to finish: The International Astronomical Union names all colles (small hills) on Saturn's moon Titan after characters in Tolkien's work; in 2012, they named a hilly area "Arwen Colles" after Arwen.
