Joel is one of those boys' names that's never been super-popular yet has never been UNpopular either -- it's been in the Top 400 in the US since we started keeping statistics in 1880, and It still ranks at a surprisingly strong Number 159. So it's inevitable that its female form Joelle would gain visibility too, and indeed Joelle was used most widely during Joel's reign in the Top 100, from the late 1960s through the early 1990s. But here's the important thing to know: Although Joelle fell off the Top 1000 more than a decade ago, it swims just beneath visibility, with 241 baby girls named Joelle in one recent year. And like many other French names for girls, Joelle also ranks high in the Netherlands. Pronounciation is distinctively two syllables, as if it were two names: Jo Elle. Joel, on the other hand, rhymes with bowl and roll.
