The unnamed baby

Sullivan is a jaunty Celtic three-syllable name, with a real twinkle in its eye. It was immortalized in the 1930s classic film Sullivan's Travels and was chosen for one of Patrick Dempsey's twin boys. Nickname Sully is equally jaunty.

Classic and elegant but with boyish charm, Theodore has become hit name in recent years, vaulting into the US Top 10 in 2021 for the first time ever and into the Top 5 in 2024. A favorite in English speaking countries, it also ranks highly across the UK and Ireland, and in Canada, New Zealand, and Australia.

Titus, once seen as a slightly forbidding Roman, New Testament, and Shakespearean name, was brought back to contemporary life in the USA by the TV series Titus 2000, increasing in popularity along with other revived ancient names like Linus and Silas.

Will has definitely replaced Bill, not only as a nickname for William but as a stand-alone name as well, partly thanks to England's Prince William, also known as Wills. Currently outside the Top 1000 in the US and the UK, it wouldn't feel totally out of style.

Willa has become increasingly fashionable, with its combination of Willa (born Wilella) Cather-like pioneer strength and the graceful beauty of the willow tree.

Willoughby is an energetic last-name-first route to the popular short form Will, livelier than any of the two-syllable options. It could be picked up by parents attracted to the Willow sound for girls.
