      Greek, Hebrew
    • Meaning:

      "my strength is God"
    • Description:

      A cool Biblical option that currently sits just outside the US Top 1000, Ozias gets extra points for its user-friendly nicknames Oz and Ozzie. Given to around 200 boys in 2023, it has quadrupled in use since 2013.

      Deriving from the Hebrew Uzziah, Ozias is the name of several minor figures in the Greek and Latin Bible, most notably the king of the ancient Kingdom of Judah. It also has a literary connection in the form of the wonderfully named Ozias Midwinter from Wilkie Collins' 19th century sensationalist novel Armadale. Several characters in the novel describe the name as 'horrible', claiming that 'no sane human being would assume such a name as Ozias', but we - and a growing number of parents - would disagree.

      Latin and English
    • Meaning:

      "bear cub"
    • Description:

      In the past, Orson has felt like a one-person moniker, tied to film director Orson Welles, who dropped his given name of George in favor of his more distinctive middle. While the Citizen Kane creator seemed to own the name during his lifetime, it's now an interesting possibility for any parent seeking an unusual yet solid name. It's started to appear to the celeb set too -- both Paz Vega and Lauren Ambrose have little Orsons.
