The London Times Birth Announcements

Imogen has long been fashionable in England and is gaining favor in the US among stylish parents. Pronounced the British way — the initial i is short as in Kim, as is the final E as in Ken — Imogen is as pretty and classy as it is distinctive.

Isaac has shaved off his biblical beard and leaped into the upper echelon of popular boys' names, outrunning cousin Isaiah. A favorite of the Puritans, Isaac has never dipped below Number 400 on the US list of top boy names.

Isabella has been a Top 10 name for girls in the US for two decades now. The Latinate form of Isabel, a variation of Elizabeth which originally derived from the Hebrew name Elisheba, Isabella reigned as Number 1 in 2009 and 2010.

Isabelle is the French variation of Isabel, which emerged in the Middle ages as an Occitan form of Elizabeth. Medieval queens Isabella of Angoulême and Isabella of France helped popularize the name in the United Kingdom. Isobel is the Scottish version, Isabella the Italian, and Izabel is used in Brazil.

Isla is a hit name throughout the English-speaking world but hasn't found the same popularity in other western countries, perhaps because its spelling and pronunciation don't make sense for those whose native language is not English. Think island without the final two letters.

The Scottish spelling of Isabel has a definite character of her own, the 'o' giving her an extra infusion of strength but also an element of confusion. How do you pronounce that? Answer: Exactly like Isabel or Isabelle.

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular boy names starting with J.

Jago is a dashing alternative to overused favorite Jacob.

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.

The cool form of James in the 1970s and '80s for both sexes. Still a more stylish short form than Jimmy, though many parents will want to call James by his entire, not-very-long name.

No, we don't consider Jane too plain. In fact, for a venerable and short one-syllable name, we think it packs a surprising amount of punch, as compared to the related Jean and Joan.

Jasmine was derived from the Persian word yasmin, referring to the jasmine flower. Scented oil was made from the plant, and it was used as a perfume throughout the Persian Empire. Variants include Jazmin, Yasmin, Yasmine, and Jessamine.

Jasper originated as a variation of the Latin Gaspar, which ultimately derived from the Persian word ganzabara, meaning "bringer of treasure." As a given name, Jasper’s etymology is unrelated to that of the gemstone, which comes from a Semitic word meaning "speckled stone." Jasper is the usual English form for one of the Three Wise Men who brought gifts to the infant Christ according to medieval tradition and appears in the Bible as a reference to the stone itself in Revelations 4:3.

Jemima, the name of a strong and beautiful Biblical daughter of Job, has long been among the chicest choices of aristocratic Brits, most recently ranking at #231 there in 2017. But despite its lovely sound and peaceful meaning, this attractive name hasn't ranked in the US Top 1000 since 1893, no doubt due to the problematic association with racial stereotyping, exemplified by the Aunt Jemima brand of pancakes.

Jennifer is the Cornish variation of Guinevere, which ultimately derived from the Welsh name Gwenhwyfar. It has been in use in the English-speaking world since the 18th century but came to prominence in the 20th. Playwright George Bernard Shaw chose Jennifer for the name of his leading lady in his play The Doctor’s Dilemma, which drew more attention to the name.

When Jennifer finally gave up her Number 1 place on the girls' popularity list, her crown was passed to Jessica, who reigned for not one but two decades. Jessica was the Number 1 name in both the mid-1980s and 1990s, never sounding quite as trendy as its predecessor, maybe because of its classic Shakespearean pedigree.

The Jodie spelling might be even more obscure, at this point, than the fading original, except actresses Jodie Foster and Jodie Sweetin have kept it in the public eye.

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.
