If you’re drawn to boy names that start with “O,” chances are you’re already familiar with Oliver and Owen. The two monikers are ranked Nos. 3 and 18, respectively, on the 2022 popular baby names list from the Social Security Administration. But have you heard of Obadiah?

“Oliver and Owen have really dominated in the past generation. But we’re seeing more Obadiahs, which is a biblical name," Laura Wattenberg, creator of Namerology, tells TODAY.com.

The names Ozzy and Otto are also picking up steam, according to Wattenberg. Oslo, as in the capitol of Norway, is is another “O” name that is gaining in popularity.

“Geographic names, like Oslo or Cairo, are trendy right now,” Wattenberg explains.

For parents in search of an unusual name for their bundle of joy, the letter O is a good place to start.

“If you choose an 'O' name that isn’t Owen or Oliver, it’s probably going to be unusual,” Wattenberg says. “There aren’t many traditional 'O' names.”

Famous male personalities with “O” names throughout history include: Owen Wilson, Odell Beckham Jr., Oscar Wilde, Orlando Bloom, Orson Welles, Otis Redding and Olivier Martinez.

Celebrities who have chosen “O” names for their sons include: Odin (Nick Carter), Oliver (Dylan Dreyer), Onyx (Iggy Azalea) Ozzie (Mandy Moore), Oscar (Gillian Anderson), Otis (Jason Sudeikis), Ozzie (Max Greenfield), Ode (Jena Malone), Odie (Ashley Williams), Orson (Lauren Ambrose) and Oskar (Nate Berkus).
