I've only met one person named...

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.

Taina is a feminine Tupi name meaning "star." A nice choice for those looking for something celestial but less common than Stella or Astrid. Taina also means "secret" in Russian and is a Finnish form of Tatiana.

Taj is a cool-sounding name reflecting the magnificence of the seventeenth-century Indian Taj Mahal, chosen by Aerosmith's Steven Tyler for his son.

One of the hot two-syllable T names of the nineties (along with Tyler, Trevor, and Taylor), and well represented on soap operas; Tanner is still widely used, but its popularity is declining.

Tempest is one of those names that could go either way. Cool, evocative modern word name? Or asking for trouble? Your call, but if you decide the former image is dominant, be warned that some people will see it as the latter.

Few people would have considered the surname of this famous Victorian poet as a first name until Russell Crowe chose it for his son in 2006. But, as a rhythmic three-syllable patronymic, Tennyson has a lot going for it, not least of all the appealing nickname Tenny; it would make a novel choice for the son of a Dennis.

A fresh update to Tara.

Theron is best known these days as the surname of actress Charlize, but it does have a long history as a first name, ranking in the Top 500 in the early part of the 20th century and only dropping out of the Top 1000 in the early 1990s. Theon is a similar name made familiar by the popular series Game of Thrones: Might it and Theron rise in tandem?

The Finnish cognate of Thea, from Dorothea.

A fairly common Hebrew name without much crossover potential.

An interesting and attractive bicultural choice--the Hebrew version is used for babies born in spring, when turtledoves arrive--especially as a middle.

Tulia, rhyming with Julia, is one of several offshoots of the noble Roman family name Tullius, best known as the middle name of the philospher Cicero. Another option is Tullia with a short u. This whole clan of names is relatively unknown but may be rediscovered thanks to the fashion for ancient Roman names.

The Turkish name for the Danube River. Tuna is technically a unisex name in Turkey, yet it is more common among boys.
