Mavis, another word for the song thrush, is also a relative of the Welsh word for strawberries, mefus. Mavis has something of a British World War II feel, a friend of Beryl and Doris, but it was quite popular in the U.S. a couple of decades earlier, peaking in the Roaring Twenties.

Scout, a character nickname from To Kill a Mockingbird (her real name was Jean Louise), became a real-life possibility when Bruce Willis and Demi Moore used it for their now-grown middle daughter, followed by Tom Berenger a few years later.

A unisex choice that is growing in popularity for both genders—but given to girls about four times more often than to boys.
