Marty is one of those Old Man nicknames that's just starting to sound cute again.

Britney Spears' little sister Jamie Lynn was one of the first to put this nickname on the birth certificate. Cute for a child, but we recommend giving her the option of the full name for later use.

Spike is part mid-century nickname-name, ala Buster or Buck, and part word name, with an all-over cool creative dude feel thanks to directors Spike Lee and Spike Jonze. Mike Myers named his son Spike. That's right: Spike and Mike. Spike qualifies as one of the distinctly American names.

With the rise of ancient Roman names, Octavian suddenly seem plausible again. A variation of Octavius and relative of the more modern Octavio, it's an equally attractive member of the trio.

One of the first luxury brand names and the quintessential Booming Eighties status-conscious moniker; used by Donald Trump for his daughter, Tiffany has plummeted far from its high in the Top 25.

Just like Sam and Ben, Tom could be revived as a simple, well liked name on its own. Tom, just Tom, is one of the Top 100 Boy Names in France

A nickname with quirky, old-fashioned charm, Tipper likely comes from the Irish surname, Tabar, meaning "water pourer", though it may also just be used as a playful pet name for a girl, if it happens to suit. Former Second Lady of the United States, Tipper Gore (born Mary Elizabeth), is possibly the most famous bearer, having been bestowed the nickname because her favorite childhood lullaby was "Tippy Tippy Tin".

Like Papa name Rudolf, Rolf never quite emigrated from the Bavarian Alps. You might want to move on to Rollo or Wolf.

Short form of Donald -- or more stylishly, Donahue or Donovan -- that's acquired a new sixties-era suaveness thanks to Mad Man Don Draper. The name also carries a Sopranos or Godfather-style double entendre.

This spelling adds a little more femininity to the neutral Lee. Leigh and sister Lee were quite popular in the 1960s and 1970s among the first cool wave of unisex names for girls, but now have vanished from the Top 1000. The Biblical Leah is preferred.

Like Marvin and Melvin, Sheldon has been perceived as about as far out as you can get, though there are very pretty towns in Devon and Derbyshire that inspired it. Sheldon Lee Cooper is the lead nerd character on the TV hit The Big Bang Theory, giving the name a brainy image. Nickname Shel (as in Shel Silverstein, author of Where the Sidewalk Ends) could, in the modern world of nature name love, be seen as beach evoking.

Ever since the enormous German cannon was dubbed by Allied soldiers "Big Bertha" in World War I, this name hasn't worked for a sweet little baby girl. But this was not always so. Hard as it might be to imagine now, Bertha was a Top 100 name until the 1930s, and in the 1880s was the seventh most popular name in the land--the equal of Joseph.

Fauna is the Roman goddess of the earth as well as one of the fairies who protected Disney's "Sleeping Beauty". It can also be considered a word name with a scientific, nature focused feel. Used to as a way to refer to all the animals in a particular area, habitat, or time period, many might think of the phrase "Flora and Fauna" on seeing the name.

This intriguing Scandinavian name is associated with Roald Dahl, author of the juvenile classics James and the Giant Peach and Charlie and the Chocolate Factory. You can honor an ancestral Ronald just by dropping that middle 'n'.

Puck was Shakespeare's mischievous pixie who'a had a few television incarnations in more recent years. A popular name in The Netherlands but nowhere else, from what we can tell.

Down to earth and versatile, Becky is a popular diminutive of the classic Biblical name, Rebecca. In the US, it was most popular as a stand alone name back in the 60s, while in the UK, it remained in the Top 300 right up until the early 2000s.

Old-school nickname ala Spike and Babe that's favored by some hipster parents.

An approachable mini name that could go on the birth certificate, but may work best as a nickname. Full name options include Thaddeus, Theodore, and Thomas, which was the given name of Abe's son Tad Lincoln. Taddy is a rare alternative to Teddy.
