Rainbow Baby Names you have not heard of

Matthew was the third most popular boys' name in America throughout the 1980s and '90s, and is still one of the top boy names starting with M. The New Testament Matthew is the epitome of the fashionable classic—safe and sturdy, yet with a more engaging personality than John or William.

Medora is a Greek name much less common here than, say, Melanie or Melissa. It has some literary references, including as the beautiful and passionate heroine of Lord Byron's poem The Corsair, and in Edith Wharton's The Age of Innocence, there is a character named Marchioness Melora Manson.

Mercedes is one of the few names attached to luxury living that we can wholeheartedly recommend, it being a legitimate Spanish appellation stemming from one of the epithets given to the Virgin Mary--Santa Maria de las Mercedes, or Our Lady of the Mercies. The car, by the way was named after the eleven-year-old daughter of the Daimler company's French distributor in 1901.

Part of the vogue for French-sounding names in the 1920s and 30s, Nadine has been replaced by the Russian sound of Nadia and Natasha.

This female form of Nathan can be pronounced with three syllables or four.

Nathaniel was derived from the Hebrew name Netan’el, meaning "gift of God," composed of the elements natan, meaning "to give," and ’el, in reference to God. The name is featured several times in the Old and New Testaments, typically spelled Nathanael. In the New Testament, Nathanael is also known by his other name, Bartholomew.

A joyous, celebratory-sounding name.

Pandora has occasionally been used by the British gentry (for girls with brothers who might be called Peregrine) and is now starting to be heard in the US too: It was given to 34 baby girls last year.

Priya originated in India as a name derived from the Sanskrit word for "beloved." In India, where names are often given based on one’s birthday and horoscope, Priya is traditionally given to girls born in August. Priya is used in Hindu mythology as the name of a daughter of King Daksha—known for fathering 146 daughters.

Loving choice.

Shai, pronounced like shy, might morph to rhyme with may among native English speakers. This simple and attractive name is sometimes confused with or anglicized as Shay or even the Irish Shea.

Shai is a name newly-used in the US for both boys and, slightly less often, girls. Though the correct pronunciation is "shy", many will say shay, which might be all right with you.

Thea is a diminutive of names ending in -thea, including Dorothea, Althea, and Anthea. It is also the Anglicized spelling of Theia, the Titan of sight, goddess of light, and mother of the moon. She was the consort of Hyperion, and mother of Helios, Selene, and Eos.

Theodora is one of the most revival-worthy of the charmingly old-fashioned Victorian valentine names, softly evocative but still substantial, as is the reversed-syllable Dorothea.

As unlikely as it may seem, Theodore is a hot new hit name, vaulting into the Top 10 in 2021 for the first time ever and rising three more points last year to rank at Number 7.

This feminine form of Theodosius has long been buried deep in the attic, but might be a good discovery for the parent who wants to move beyond Theodora. Vice President Aaron Burr named a daughter Theodosia ("Dear Theodosia" is a song in the smash musical Hamilton), and it was the birth name of silent screen vamp Theda Bara. Theodosia actually appeared on the US popularity lists in the 1880s and 90s.
