In HBO's Game of Thrones, Bronn is an amoral mercenary raised to the knighthood through his connection to the regnant Lannister family. The homophony with "brawn" probably isn't an accident -- he's a top-tier swordsman -- and may be a turnoff to some parents. Brock and, to stay in Westeros, Bran are probably more user-friendly.

Bronn

Brevan

Rare and distinctive name with intimations of antiquity, also a Shakespearean character. 

Cleon

Leathery, masculine image, complete with user-friendly short form. 

Cordovan

Cirdan

Corbeau

Swashbuckling name worthy of a hero in a romance novel. Deveraux or Devereaux is drawn from the River Eure in France. Mick Jagger has a son named Deveraux.

Deris

This appealing Hebrew name is heard in Israel, and would fit in well with all the popular El-starting <a href="https://nameberry.com/boys-names">names for boys</a>, such as Elliot and Ellery. It was given to just five American boys in 2015. Also worth considering is the pretty female version, Eliora.

This name of the courteous Knight of the Round Table, the nephew of King Arthur, has long been superseded by its Scottish form, Gavin.

If you're looking for an Irish last name that moves beyond Casey and Cassidy, this one is pleasant sounding and worth considering. Kavanaugh, which can also be spelled Cavanagh, Cavenagh, Kavanagh, and Cavanaugh, is one of the few traditional Irish surnames not to start with Mc or O'.  Kavanagh relates to the name first Kevin or Caomhan.  Early kings of Leinster bore the name Kavanaugh.

Lancel Lannister is a minor character in Game of Thrones (the son of Kevan Lannister and first cousin to Cersei, Jaime and Tyrion) who plays a key part at several dramatic junctions in the series.

Loman is one of those rare names that is at once simple and very unusual, with fewer than five baby boys given the name in the US in the most recent year. 

But Loman does carry a few less-than-optimal association, one with tragic character Willy Loman in Death of a Salesman and the other with the symbolic meaning of that name, which literally means "low man". You might want to consider Logan or Lorcan.

The association with the infamous Nero, the fiddling Roman emperor, would be unavoidable. But there was also the detective Nero Wolfe, hero of many mystery stories.
 Nero was born Lucius Domitius Ahenobarbus, and Lucius might be a preferable choice if you know anything about ancient Roman history.

Bland compared to the Irish-sounding O-starting names, but fans of football star Odell Beckham Jr. may like the name for other reasons.

Pax, one of the variations of <a href="https://nameberry.com/list/411/baby-names-that-mean-peace">names meaning peace</a> that are newly popular in these less-than-peaceful times, got a lot of publicity when chosen by Brad & Angelina for their Vietnamese-born son. Parents attracted to Pax may also want to consider Paz, the unisex Spanish version, or Paxton, a growing-in-popularity surname choice that shares that magical X-factor.

A surname occasionally used as a first, as in former attorney general Ramsey Clark. This spelling is now closely associated with the psychopathic Game of Thrones villain Ramsay Snow (later Ramsay Bolton), and so is probably best avoided as long as the show and books are popular.

Ramsay

Unusual surname occasionally used as a first.

Rennon

Has a legitimate first name history in its native land and an appealing meaning, but pronunciation is far from obvious.

Actress Jaime King gave her son Leo the middle name Thames, for the famous London river where she and her husband Kyle Newman were married.  Thames is pronounced tehms, not necessarily common knowledge in the US. The etymology of the word Thames is uncertain, and may mean dark but more likely stems from an ancient word for river.

Thames

Torvald, not to be confused with Torvill of skating fame, is a Norse name which might be of interest to parents looking for Thor-related options. Torvald is most familiar in the English-speaking world as the infuriatingly sexist husband of Nora in Ibsen's play A Doll's House, which may account for its low usage. However, Linus Torvalds, inventor of Linux , might put the name into a more positive light, especially in Silicon Valley.
