Complete with easy, breezy and cool nickname Cal, it climbed more than 60 places in the US in 2024, placing it just outside the Top 150.

Henry is well and truly back in style. The classic returned to the Top 10 in the US in 2021 for the first time in over a century, and as of 2024, sits at Number 6. Like James and Theodore, Henry is a strong, traditional name that also manages to feel stylish and gentle.

Long popular in Ireland and England, Kieran, the name of Ireland's first-born saint and twenty-five other saints, has been building its U.S. fan base thanks to its strong and attractive sound, and its fashionable Irish brogue. While Ciaran is the more authentic Irish spelling, Kieran is more popular this side of the Atlantic.

Iconoclasts though we may be, we like Fred, we like Frank, and we like George, which was among the Top 10 from 1830 to 1950, when the number of little Georges started to decline.
