A variant of the surname Cannon, or an English word name with several possible meanings. A canon is a clergyman, as well as a rule or law – especially within religious doctrine. In the arts, canon is also the name of the whole oeuvre or work of a particular writer or creator.

Of the names derived from titles, this is one of the least obvious (unless you are of German extraction). Chancellor also has the attraction of offering the exciting - and very on-trend - nickname Chance.

Churchwarden

This name was transposed from the word for a church officer to a baby name when Reese Witherspoon and Ryan Phillippe chose it for their son, after a baseball player ancestor, and Don Johnson followed suit. Its popularity also got a boost from Nashville character Deacon Claybourne -- only to fall a bit in recent years.

Deacon

Dean may sound to some like a retro surfer boy name, but it is once again climbing up the popularity chart in the USA. For decades it was associated with Dean (born Dino) Martin; more recent representatives include Dean Cain, Dean McDermott and Dean Koontz -- not to mention Jared Padalecki's dreamy Dean Forester in Gilmore Girls.

Diakonissa

Anyone who's seen "The Book of Mormon" or visited Utah knows this as the title taken by male Mormon missionaries during their term of service. We'd advise anyone who lives somewhere with any significant Mormon population to avoid it for that reason. That said, Elder does have some history as a boys' name, especially in Latin America, where the stress is on the second syllable. The "el-" sound has become extremely fashionable, so we wouldn't be surprised if this started climbing up the charts.

The name Parson might have seemed ridiculous even a few years ago, but when Reese Witherspoon and Ryan Phillippe named their son Deacon, they opened up a whole new field of ecclesiastical cool.  Bishop, Priest, and Pastor are other possibilities.

Parson

Pastor might be a brother for Parson and Deacon. 

Pastor

An extreme example of the newly possible ecclesiastical brotherhood that includes Deacon and Bishop. This one might work better in the middle spot. 

Priest

Prior

With the new fashion for occupational names, we may hear more of this one.

Saint as a descriptive word name was first chosen by rocker Pete Wentz for his younger son (baby brother is Bronx), and now Kim Kardashian and Kanye West have catapulted the name into the celebrity stratosphere by choosing it for their baby boy. The couple called their baby "Saint" throughout the pregnancy because his conception had been so difficult. Saint was named in our predictions for the top baby name trends of 2015, on descriptive word names which also include Royal and Noble, King and Rogue. Saint is moving beyond the group of names that are only <a href="https://nameberry.com/fameberry">celebrity baby names</a> and into the general lexicon.

Shepherd is an occupational surname with a pleasant pastoral feel. It was chosen for their son by the Jerry Seinfelds, which might inspire others to follow their lead.
 There are other spelling choices--Shepard, Sheperd, Sheppard--all of which lead to the friendly nickname Shep. Artist Shepard Fairey (original first name Frank) gained a lot of attention for his Obama HOPE poster.
 Those various spellings are reflected in the surnames of such notables as astronaut Alan Shepard, "Winnie the Pooh" illustrator Ernest Shepard, actor/playwright Sam Shepard, "A Christmas Story" writer Jean Shepherd, Fox News anchor Shepard Smith, and actress Cybill Shepherd. Shepherd might be thought of as one of the out-of-the-box <a href="https://nameberry.com/list/412/christmas-baby-names">names for Christmas babies</a>.

Sister is an old-timey nickname-name for girls, ranking in the Top 1000 as a proper <a href="https://nameberry.com/girls-names">name for girls</a> until the beginning of the 20th century. But more often, Sister was used as a nickname in the truest sense of the word, not a short form ala Kathy but a nickname in the way that Chip and Bud are. Or maybe Junior is a more appropriate name analogy: Sister was sometimes the nickname given to the only girl in a family of boys, so literally a descriptive word name like Junior. 
In the most recent year counted, Sister was given as a full name to zero baby girls in the US and was probably used in a casual way by not that many more.

Succentor

Strongly associated with the mega-popular single-named singer, who was actually the fourth Usher Raymond in his family. He could start a fad.
 
The Yiddish variation of Usher is commonly used in the Hasidic community.

Christian Occupation Names

Inspired by Reese Witherspoon's son Deacon Reese Philippe and my personal love of the name Shepherd "Shep", here's a list of names having to do with occupations in any Christian church. Not all are considered occupations, as in job professions, but all are nouns describing something related to Christianity.
