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