Sybil: Baby Name of the DayLooking for a stylish – but rare – name for a daughter? Consider Sybil.

Thanks to Another for suggesting our Baby Name of the Day.

Sybil: Ancient World

Once upon a time, Sybil wasn’t a given name at all.

It was a title.

In the ancient world, it referred to a prophetess. While their personal identities remain largely unknown, their cryptic pronouncements influenced the course of history.

Certain shrines were especially well-regarded. At Delphi – arguably the most famous site – the head priestess was known as Pythia, and channeled the predictions of Apollo. The priestess at Cumae might have predicted the birth of Jesus. Plato, Virgil, and Heraclitus all recorded tales of their prophecies.

Sybil: Sybilla

In the Middle Ages, Sybilla became the preferred form. The Dictionary of Medieval Names from European Sources lists dozens of variations, including Sibilia, Sibella, and Sibly. Surname Sibley evolved, too.

How could a pagan prophetess inspire medieval namers? Because at least one revelation involved the birth of Christ, the name became acceptable in a Christian context.

Royal and aristocratic Sybillas included:

  • A queen of Jerusalem, who reigned from 1186 to 1190. She belonged to the House of Anjou, and was not the first to bear the name.
  • Henry I of England and his mistress, Lady Sybilla Corbet, had a daughter, also named Sybilla. She became Queen Consort of Scotland.
  • At least two other queen consorts wore the name in the same era.

By the Renaissance, the ancient oracles had become a popular theme in art. Michelangelo’s Sistine Chapel includes five.

The Reformation cooled enthusiasm for this name.

Sybil: Nineteenth Century Revival

The name was rediscovered in the nineteenth century. Benjamin Disraeli called his 1845 novel Sybil, or The Two Nations.

Then came:

  • Writer Lady Sibyl Primrose Grant penned short stories and poems in the 1910s.
  • Silent film star Sybil Seely appeared alongside leading men like Buster Keaton.

Sybil: Spelling

By the early twentieth century, parents clearly preferred the y-first spelling.

In 1920, when the name reached peak popularity, the y-first spelling ranked in the Top 300, while Sibyl languished 200 or more places behind.

Sybil: Fade

The name left the Top 1000 entirely after 1966.

1973’s Sybil was said to be the true story of a woman with multiple personality disorder. The bestseller became a made-for-TV movie in 1976.

Sybil served as a pseudonym for the patient, Shirley.

Cybill Shepherd – named for grandfather Cy and father Bill – played Jacy in The Last Picture Show in 1971, and later dominated the 1980s as one-half of the duo in Moonlighting.

The combination led to a small uptick in the number of girls given the name, as well as the debut of Cybil and Cybill. But by the mid-1990s, it teetered on the edge of obscurity.

Sybil: Trelawney and Crawley

Today’s parents will see Sybil in a very different light.

First came Harry Potter divination professor Sybill Trelawney, the maker of the very occasional – but critical – prophecy.

But it’s Downton Abbey that remade the name. The BBC breakout hit centered on the Crawley family, including idealistic youngest daughter Sybil. She’s a suffragette and a nurse during the war. She elopes with the chauffeur, only to die during childbirth. Their daughter – usually called Sibby – is named after her mother.

Downton Abbey has done wonders for Cora, so it comes as no surprise that the name is trending. 90 girls were named Sybil in 2015, the highest number since 1980.

That’s still far outside of the current US Top 1000, which makes this a great choice for parents seeking something just as simple as Alice or Evelyn, as ancient as Penelope, but far less expected than any of the current favorites.

Do you think Sybil will return to the US Top 1000?

  1. Sybil is such a darling name that reminds me of Sybil Ludington from Paul Revere’s ride.

  2. Sibyl, or possibly the Irish variant Sibéal, is on my list as a way to pass down my maiden name Sibley.

  3. I like Sybil for the nickname Billie. (Billie was the childhood nickname of my grandmother.). I imagine other parents attracted to names like Charlie for a girl might also go to Sybil.

  4. Technically, even though Downton Abbey may have been shown on the BBC in the US the initial British run was on Itv1 (abit like the standard third channel on a US tv).

  5. Oh, Sybil. She’s actually been on my list for almost 5 yrs-when I was naming Phoebe. I love the feminine-but-not-frilly genre, and the quirky-without-being-weird category. She’s still on our short list, but I’m keeping an eye on her for now.

  6. Sybella is rather a fashionable favourite in Australia, and has been for a few years (multiple variant spelling).

    I’ve been waiting for Sybil to take off on the back of this success, but haven’t seen much evidence of it so far.
