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. With the renewed interest in names ending in 's' — and in bird names — Mavis could make a return, especially with the new interest in Maeve, and in fact, it reentered the US Top 1000 after a 50-year absence in 2016.

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—it was picked by skater Tai Babilonia for her son and Kerri Walsh for her daughter Scout Margery.
