Siobhan is the Irish variation of Joan, which is derived from the ancient Anglo-Norman name Jehanne. In this way Siobhan is indirectly related to the name Sinead—the Irish form of Jeannette, which also derived from Jehanne—although Sinead is not a nickname for Siobhan. Siobhan was the name of several early Irish queens and was introduced to the American public by the actress Siobhan McKenna.
 
Siobhan is a lovely Irish name which has spawned many Anglicized variations, but using the original form preserves the integrity of one of the most beautiful <a href="https://nameberry.com/baby-names/804/irish-names-for-girls">Irish girls' names</a>.
 
There have been a wide variety of fictional Siobhans, from a Detective Sergeant in the John Rebus novels to a vampire in Stephenie Meyers's Breaking Dawn to a character in J. K. Rowling's The Casual Vacancy. Most famous these days is the only daughter Siobhan in TV's Succession, appropriately nicknamed Shiv.

Sounds like Serena, but refers to the mythological sirens -- half woman, half bird -- who virtually sang men to death. Not a great role model for your little girl.

The image of the lovely Lady Sybil, tragic youngest daughter of the Crawley family on Downton Abbey is likely to go a long way towards reviving this almost forgotten name, off the list since 1966 and most popular in the 1920s and '30s. 
 Sybil is the most common spelling of a name which the Ancient Greeks used as the generic word for a prophetess--a woman who claimed to be able to interpret the wishes of the gods through their oracles. The term was later transferred into Christian theology where the sibyls were celebrated as having divine knowledge, which in turn brought the name into common use in the Middle ages. 
 Benjamin Disraeli wrote an influential political novel titled Sybil, which increased the popularity of the name in Victorian times, its use having suffered after the Protestant Reformation. More recently however, the name was severely undermined by the eponymous book and 1976 movie based on the character of Sybil-- played by Sally Field-- whose multiple personalities have now been confessed as fake.
 There is also a Sybil in Oscar Wilde's The Picture of Dorian Gray and Sybill Trelawney is a witch and seer in the Harry Potter books, a Professor of Divination played on screen by Emma Thompson. Actress Cybill Shepherd, on the other hand, bears an invented name combining those of her Uncle Cy and Dad Bill.
 
Clunky-cute-and-cool, Sybil is a Nameberry gem, ranking in the Top 200 - and this popularity is beginning to reflect on the real world. Back in 2012, Sybil was given to less than 20 girls a year in the US; by 2013, it was chosen for nearly 70 -- and the most recent count, 136 girls were called Sybil, making it similar in popularity to Daenerys and Yesenia.
