Ansel, primarily associated with the great western photographer Ansel Adams, famed for his magnificent photographs of the Yosemite Valley, could make a creative artist-hero choice. For Adams it was a family name – he was named after his uncle, Ansel Easton. And, in turn, Adams was the namesake of young heartthrob Ansel Elgort, son of a photographer.
 Derived from the same root as Anselm, Ansel is a medieval Germanic name that still feels fresh and stylish today.
 Ansel has been far from a <a href="https://nameberry.com/list/317/unique-baby-names">unique baby name</a> – it was on and off the popularity lists in the late nineteenth and early twentieth centuries, reaching as high as Number 540 in 1893.

Arden is a gender-neutral name that's sleek and stylish but always seems to bob just below the surface of popularity, despite ticking all the boxes with its fashionable two-syllable, N-ending shape and its awesome nature-inspired meanings. In the 2021 US statistics, 41 percent of the babies named Arden were boys to 59 percent girls.

 A locational surname name deriving from several places in England, there are multiple legitimate derivations for this name. One is from Old English earn "eagle" + denu "valley", while another is from the Celtic ard meaning "high".

Quirky cool Arlo is now well and truly back. Last year it broke into the US Top 200 boy names and consistently ranks among the most popular boy names on Nameberry. 
 Arlo is even more popular in the UK, Australia and New Zealand. Arlo is also one of the top baby names among Nameberry's visitors from leading US cities.

 
Once strongly associated with shaggy singer Arlo Guthrie, Arlo has an animated and cheery feel, thanks to its upbeat o ending. It was chosen by Toni Colette for her son in 2011, which brought the name back into the spotlight. Previously, Arlo was in regular use in the first half of the twentieth century—it was Number 667 in 1915, for example, but it had dropped off the charts in 1944.
 Arlo has many possible derivations along with its Irish and English roots. It may be a shortened form of the Italian name Carlo or the Spanish Carlos, and in Basque-speaking regions it is the word for area. In English, Arlo was used as a place name, Arlo Hill, by Edmund Spenser in his epic poem The Faerie Queene and is thought to derive from the Celtic word Aherlow, meaning "between two highlands."

 A growing number of girls are also named Arlo in the US each year, with a handful more babies of both sexes receiving the Arlow and Arlowe spellings, which take this name more into smart surname territory.
