English and British Royal names from 1066

As a highly popular girls' name in all Spanish-speaking countries, this saintly Latin variation of Mary retains a timeless beauty. Through the centuries, Maria remains one of the most widely-used girl names starting with M.

Patricia still sounds patrician, though its scores of nicknames definitely don't. Wildly popular from the forties (alternately Number 3 and 4 throughout the decade) to the sixties, Patricia has been fading ever since. But a comeback in its full form is definitely conceivable—just look at Penelope.

The popular appeal of the strong, intelligent Saint Teresa of Avila, combined with the selfless compassion of the more recent Mother Teresa, have fused to give this second-tier classic a somewhat noble, religious image. Although the origins of the name are uncertain, it has been prevalent particularly in forms Theresa, Teresa, and Therese throughout Europe for centuries.

Casimir, a traditional name of Polish kings, could do quite well these days as we see the rise of Caspian, Cassius, Castiel, et. al. Like Leopold and Laszlo, Casimir is strong and worth considering if you've got an adventurous streak — and bet your son will too.

Lionel is one leonine name that hasn't taken off as cousins Leo and Leonardo have, though it did reenter the Top 1000 in 2010 after several years away; it was at its highest point in the 1920s and 1930s.

Duncan is jaunty, confident, and open, a Scottish royal name that's brimming with friendly charm and makes it into our golden circle of names that are neither too popular nor too strange. Popularity aside, Duncan is one of the most classic Scottish names for boys.

Augusta is a dignified name reminiscent of wealthy great-aunts and stately homes, but with the fashion for both August and Gus for boys, and the renewed interest in clunky classics like Gwendolyn and Winifred for girls, Augusta might just appeal to contemporary parents.

Agatha until recently summoned up visions of martyred saints, mauve silk dresses, and high lace collars, but now that some dauntless excavators have begun to resurrect it, we're sure more will follow their lead. Actor Thomas Gibson used it for his daughter in 2004.

Dorothea is a romantic Victorian-sounding name that blends elegance, gravitas and a hint of clunkiness too. Popular in the early decades of the twentieth century, it has been off the charts since 1970, however it's definitely on the brink of a revival! In fact, it has already been making its way back into the UK Top 1000, and a recent year saw it given to 90 girls in the US — three times the number it was given to a decade prior.

Angela was a Top 10 name from 1965 to 1979, the fifth most popular name for three years, and staying in the double digits until the turn of the 21st century. Today, though, Angelina or Angelica would be more fashionable options.

Donald has been used for centuries in Scotland, where the Macdonald clan is one of the most ancient and where there have been six early Scottish kings by that name. Donald was a Top 20 name throughout most of the early twentieth century.

This name of three early popes has been associated in recent years with a cocky cartoon cat ("Thufferin' thuccatash!") and the Italian Stallion hero of the Rocky and Rambo movies (who was born Michael) — and yet we think it just might be ready to move further back into the mainstream.

Christina, a pretty and feminine, crystal clear classic, may be trending downward, but it's never out of style. Christina's short forms Chris, Christie, and Tina all seem dated—making the royal Christina best used in its full glory.

Cultured and cultivated in an old-style, Old World way, Anton is popular across Europe. It may be associated with the classic Russian playwright Anton Chekhov and also with ballroom dancer Anton Du Beke.

Humphrey is an old name that might have faded completely were it not for that Bogie flair. A royal name in Britain, where it's used somewhat more frequently, Humphrey might just have some life beyond Bogart here, especially with the recent interest in the names of Golden Age Hollywood stars. His first name was the maiden name of his mother, Maud Humphrey, a well-known illustrator who used baby H. as a model.

How do you spell Teresa? Teresa, the simpler phonetic form of this name, was the most popular variation for its early life, when it was used exclusively in Spain and Portugal. Other spellings of Teresa include Theresa, the usual English form, and the French Therese.

Philippa is a prime example of a boy's name adapted for girls that was common as crumpets in Cornwall, but rarely heard stateside. That was before the advent of royal sister-in-law Philippa Middleton, who goes by the lively nickname Pippa.

To Americans, a quintessential British name, introduced to the U.S. public by suave journalist/PBS Masterpiece Theater host Alastair Cook. Sometimes used in the U.S. by parents with Scottish heritage.

Now seen as the chap in the smoking jacket in a 1930s drawing-room comedy, Reginald has actually been on the US popularity list every year since 1880.

Maud, lacy and mauve-tinted, was wildly popular a hundred years ago but has been rarely heard in the past fifty. Some stylish parents are starting to choose Maud again, especially as a middle. Maude is another spelling, associated with actress Maude Apatow.
