Saxon is unusual word name that nevertheless feels right on trend, with that sharp X in the middle and that two-syllable-ending-in-n pattern. Reminiscent of Roman but not yet so popular, Saxon is one to watch out for. 
 The word 'Saxon' is used to describe a number of Germanic tribes from the early middle ages, who conquered and settled in England to become the Anglo-Saxons. It is the name of numerous places, in the US, Switzerland, and Germany and it's also a 70s rock band, an alias of the recurring Doctor Who character, The Master, and the title of a series of books by Bernard Cornwall.
 
Elon Musk has a son named Saxon; Saxon Gregory-Hunt is an Australian weightlifting champion; Saxon Sydney-Turner was a member of the Bloomsbury group; and Saxon Sheffield and Saxon Kent are recent social media influencers.
 
With its slightly musical sounds, its outdoorsy but upper crust vibe, its similarities to Roman, Soren, Paxton, and Sebastian, it is no wonder that Saxon was a fast rising choice in the UK in 2022.

Tristan -- known through medieval legend and Wagnerian opera -- has a slightly wistful, touching air. This, combined with the name's popular "an" ending, makes Tristan very appealing to parents seeking a more original alternative to Christian.
 One influence was the character Tristan Ludlow played by Brad Pitt in the 1994 movie Legends of the Fall, based on a Jim Harrison novel.
 Tristan is a dragon-slaying hero of Celtic legend, whose story was incorporated into Malory's Le Morte d'Arthur, in which Tristan is one of the Knights of the Round Table, consumed by his doomed love affair with Queen Isolde. Wagner set the story to music in his opera Tristan und Isolde.
 Tristan and its alternate form Tristram have been found in later lit as well. Tristram Shandy is a famous early comic novel by Laurence Sterne (in which the hero's father calls Tristram the worst name in the universe); Tristan is a major character in James Herriott's All Creatures Great and Small, and there is an eponymous novella by Thomas Mann.
 Particularly popular in Canada, Tristan was chosen for their sons by Travis Tritt, Wayne Gretzky, Natasha Henstridge and, most recently, by Elsa Pataky and Chris Hemsworth. Basketball player Tristan Thompson hails from Canada.
 Other variants of Tristan include Tristen, Tristin, Triston and Tristian.
