Boys O

Hugo, the Latin form of Hugh, has more heft and energy than the original -- and of course we love names that end (or begin, for that matter) with an o. This one is especially appealing because it's backed up by lots of solid history and European style.

Ignacio, like Horacio, makes its gray-bearded English equivalent name sound positively dashing. While the Ig- beginning summons up such associations as ignoble and ignorant, the era for Ignacio and Ignatius and Iggy may be nigh.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Although most people don't think of it like this, Indigo might also be considered among the most stylish Greek baby names in use today. Some cultural references: The Indigo Girls are a folk duo, 'Mood Indigo' is a classic Duke Ellington jazz composition, and there is a 1970's New Age theory that Indigo children possess special, sometimes supernatural abilities. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.

An unusual name heard in contemporary Germany, the Netherlands, and Scandinavia, it's the male version of the more familiar Inga. It's the name of a German god, and attached to German-born soap star Ingo Rademacher--the father of sons named Peanut and Pohaku Zen.

Inigo, almost unknown in the U.S., is an intriguing choice, with its strong beat, creative and evocative sound, and associations with the great early British architect and stage designer Inigo Jones. The sixteenth-seventeenth century Jones shared his name with his father, a London clockmaker, who received it when Spanish names for boys were fashionable in England, especially among devout Roman Catholics.

Jago is a dashing alternative to overused favorite Jacob.

While Jairus is rare, this Spanish variation is heard in the US, having ranked in the Top 1000 for the last three decades. It currently ranks in the latter end of the charts, while similar sounding Kairo, Cairo, and Kyro rank higher.

Jethro, though the biblical father-in-law of Moses, has suffered for a long time from a Beverly Hillbilly image, but some really adventurous parents might consider updating and urbanizing it and transitioning it into the hip o-ending category.

This sleek Italian name was raised from the dead by Mexican Mozart in the Jungle star Gael Garcia Bernal, who chose it for his son (he also has a daughter named Libertad). For athletic inspiration, Lazaro Alvarez, boxing for Cuba, is the three-time world champion lightweight boxer. Lazarus and root name Eleazar are both also destined for comebacks.

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

For centuries this name was associated primarily with the towering figure of Italian Renaissance painter-scientist-inventor Leonardo da Vinci, and was scarcely used outside the Latin culture.

A vibrant, operatic Latin choice.

About 100 baby boys were named Lucio in the US last year, a number we expect to increase with the growing popularity of all names in the Lu family. It's a family united by sound, with three main branches.

Simple and universal, Marco is a Latin classic that would make a much livelier namesake for an Uncle Mark. It was used for her son by actress Jill Hennessy and goes well with surnames of any nationality.
