Ian Ziering 28386

It's another daughter for original 90210-er Ian Ziering—he and wife Erin welcomed Penna Mae exactly two years to the day after her big sister, Mia Loren, arrived.

While big sister Mia sports a very popular name, Penna's more offbeat and less heard of—it's the Latin word for feather, and an abbreviation for Pennsylvania. And it could also be used as a cool nickname for Penelope, too. But even though it's rarely heard here in the U.S., it doesn't sound too outlandish—it has a very classic vibe to it.

Mae is a variant spelling of middle-name staple May, though also it's often used as a nickname for Margaret. Its most famous association is with legendary screen siren Mae West, who was known for her classic quips, like "When I'm good, I'm very good. But when I'm bad I'm better." (She wrote many of her works, in addition to starring in them.)

Even though the siblings have names that vary considerably in popularity (Mia's currently in the top 10 in name popularity, while poor Penna doesn't even chart), they pair nicely together—both are feminine and easy to pronounce.

What do you think of the name Penna? Is it too offbeat, or a name unique enough for a very special little girl?
