    • Origin:

      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.

    • Meaning:

      "eighth"
    • Description:

      Octavia began as the Latin, then Victorian name for an eighth child.
