One of the jewel names in use a hundred years ago, due for revival along with sisters Ruby and Pearl.

Haven is a recently invented safe-harbor name that appeals to an increasing number of parents who don't want to voyage quite as far as Heaven.

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.
