I- Girls

Many vowel names stylish a century ago are coming back, and Ida seems like a possible, logical successor to Ada and Ava.

Idra is one of the less obvious botanical names. In ancient times, a fig tree was a symbol of learning, peace, and prosperity.

Imogen has long been fashionable in England and is gaining favor in the US among stylish parents. Pronounced the British way — the initial i is short as in Kim, as is the final E as in Ken — Imogen is as pretty and classy as it is distinctive.

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. 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.

The luminous Ingrid Bergman's appeal was strong enough to lend universal charisma to this classic Scandinavian name, which has been somewhat neglected in the US. Even today, a child named Ingrid would be assumed to be of Scandinavian ancestry, signaling the name has never been fully integrated into the English lexicon the way other European choices from the same era like Danielle or Kathleen have.

Serene Irene, the name of the Greek goddess of peace and one of the most familiar Greek goddess names, was hugely popular in ancient Rome and again in the United States a hundred years ago.

Iris has so much going for it. It's a fashionable flower name. It's a mythological name, from the Greek goddess of the rainbow. And it's a classic name, always ranking in the girls' Top 1000 but now at its highest point ever.

Isa is a name unto itself but might also be a short form of Isabel or Isadora. With the new popularity of Isabel and Isabella and even Bella, Isa may become more familiar.

Isabel derived from Elizabeth in southwest Europe during the Middle Ages. It was originally written as Elisabel, but the first syllable was dropped as it spread across the continent. In Spain and Portugal, Isabel and Elizabeth are considered to be variations of the same name, but they are treated as separate names in other European countries and the US.

Why is Isabella megapopular while Isadora goes virtually ignored? Too close a tie with tragic modern dancer Isadora Duncan (born Angela Isadora), who was done in by her long flowing scarf, perhaps, or with fusty male version Isidore. But we think Isadora is well worth reevaluating as an Isabella alternative. Quirky couple singer Bjork and artist Matthew Barney did just that and named their daughter Isadora. Isidora would be an alternative, just as proper but not quite as charming spelling--the one used as the spelling of a fourth century saint's name.

The Scottish spelling of Isabel has a definite character of her own, the 'o' giving her an extra infusion of strength but also an element of confusion. How do you pronounce that? Answer: Exactly like Isabel or Isabelle.

Now that Tristan has been rediscovered, maybe it's time for his fabled lover in the Arthurian romances and Wagnerian opera, a beautiful Irish princess, to be brought back into the light as well.

The quirky, offbeat and energetic botanical name Ivy is enjoying a deserved revival, propelled even higher by its choice by high-profile parents Beyonce and Jay-Z for daughter Blue Ivy. Ivy is also traditionally used at Christmas, make this one of the perfect names for December babies.
