Some people know the precise name they’ll bestow on their baby as soon as they see two pink lines appear on a pregnancy test. And then, there are those who can’t come up with a name to save their life. But even if you might not know the exact name that you’d like to give your baby, you might have fallen in love with a letter. And if you’re thinking about the 10th letter of the alphabet, these J baby names are almost too joyful.

Of all the letters in the alphabet, J is one of those that is pretty uncommon. In fact, the letter J (along with Q and Z) appear the least frequently in words, per to Grammarly. If there’s such a shortage of J words, you might think that there would be an equal scarcity of J baby names, too — but you’d be wrong. There are so, so many baby names for both boys and girls, and all start with J. You can go with tried and true classics like John or James, or go a bit more modern with Jaden or Javeon.

So if you’re jonesing for a J baby name, or just want to get a jumpstart on the whole baby-naming process, try out any of these J baby names that are just joyful.
