You may never have known a Nettie personally, but there well might be one hidden in your family history, considering that she was a Top 100 name until 1901 and stayed on the Social Security list until 1962.

Elmo, like fellow Sesame Street characters Kermit and Grover, has a hard time being taken seriously. (It isn't easy being red either.)

Nelson is a rather stiff and dated surname name that is sometimes used to honor distinguished South African activist Nelson Mandela, as Celine Dion did for one of her twin boys. Other notable associations are with the British Admiral Lord Horatio Nelson, New York Governor Nelson Rockefeller, novelist Nelson Algren and movie operetta star Nelson Eddy. It was also the given name of "Rabbit" Angstrom, protagonist of John Updike's series of novels.

Once a Top 100 name, this Spanish diminutive of Ana still retains some of her Latin flair. A notable namesake is noted attorney Anita Hill, another is the great jazz singer Anita O'Day. Plus there's Disney cred via the lead human character in 101 Dalmatians.

Verena is pleasant but old-fashioned. Whether that's the outdated kind of old-fashioned or the so-out-it's-in-again kind is your call.

Ike, once the quirky one-person nickname of President Dwight Eisenhower, has morphed into a cool kid nickname of the early 21st century.

This spelling of the classic name is found in France, Germany, Greece, and other cultures, and is worn by such notables as Elisabeth Kubler-Ross, Elisabeth Shue, Elisabeth Moss, and Elisabeth Hasselbeck. The name's pronunciation is usually just like the Z version, but some parents choose this because they want to discourage the Liz or Lizzie short forms and so pronounce it as if it has Lisa in the middle.

The streamlined Ruben is much more popular than the original Biblical Hebrew version in the US.

This traditional Germanic name hasn't been on the U.S. list since 1958, but perhaps due to the mythic power of painter Frida Kahlo, parents are beginning to show some interest in it.

Old-time nickname that's following in the fashionable footsteps of cronies Jake and Sam. Abe feels both fresher and cuter -- which is maybe the same thing? -- than those choices right now. You can also get to Abe via Abel, which may prove a friendlier formal name than the gray-bearded Abraham.

Medieval name without much of a future.

With Old European vibes, Johan is a variant of the classic John, similar to the Latin, Hebrew, and Germanic forms, Iohannes, Yohanan, and Johannes. Conjuring up the image of the classical composer Brahms or the astronomer Kepler, while still feeling timeless and distinctive, Johan has been in the US Top 600 for most of the 21st century, helped along by Heidi Klum and Seal using it for their son in 2006.

Nickname left over from the last generation.

Although they could be easily confused, Elsbeth is a fairly unusual contracted German version of Elizabeth, while cousin Elspeth hails from Scotland. With its 'beth' ending, Elsbeth feels closer to the mother name.

Once aristocratic British surname yet to be revived. Vince Vaughn recently gave his son the same double initials as his own when he named him Vernon Vaughn.

Mattie, which might be a short form of Martha, Matilda, or even Madeline, ranked among the Top 100 names for girls in the 1880s and in fact, has held a place among the Top 1000 for most of U.S. naming history. It fell off the popularity charts in 2015 and makes a cute, tomboyish option.

Alive thanks to Ponderosa papa Greene and SNL creator Michaels, both from Canada, where the name is much more popular.

Subtract the last two letters of Arnold, and you're left with a much more modern-sounding name. Arno is also the name of the main river in Florence, upon which sits the famed Ponte Vecchio. The Italian river name means "flowing water".

To those who remember, Rhoda is still reminiscent of the brassy Bronx 1970s sitcom Rhoda Morgenstern. But Rhoda has a much longer history--it is a name that can be found in the New Testament as a servant girl in the house of Mary, mother of John. Later, Rhoda appeared in the novel Vanity Fair and the Shaw play Man and Superman.

Though it was used by the Puritans in the sixteenth century, the founding of the modern Jewish state in 1948 transformed Israel from a traditional favorite into an icon of Judaism.
