Alma is a somewhat solemn, soulful name that had a burst of popularity a century ago, then faded into the flowered wallpaper, and is now finding its footing once more. 
 In addition to being familiar via the term alma mater, Alma has many cultural ties, such as Alma Mahler, a 19th Century composer and musician and the character Alma Del Mar played by Michelle Williams in the 2005 film Brokeback Mountain. Other characters named Alma have appeared in Deadwood, The Hunger Games, American Horror Story, and The History of Love by Nicole Krauss. In the Tennessee Williams play Summer and Smoke, a character named Alma explains that her name is "Spanish for soul."
 The name became fashionable in England following the Battle of Alma--named for the Russian river—during the Crimean War.
 Alma is one of those surprising names that's always been on the Top 1000, but after sinking to its lowest point ever in 2011, Alma is making a comeback. Like Ella and Ada, Alma is a name appreciated for its simplicity, integrity, and—yes—soul.

Arthur, once the shining head of the Knights of the Round Table, is, after decades of neglect, now being polished up and restored by stylish parents, inspired perhaps by the new generation of royals. Arthur has led the list of possible names for the young British princes, chosen as a middle name for Prince Louis, son of William and Catherine, Prince and Princess of Wales.
 In addition to its leading role in the Arthurian legends, Arthurs figure prominently in Nathaniel Hawthorne's The Scarlet Letter, Edgar Allan Poe's The Narrative of Arthur Gordon Pym of Nantucket and George Eliot's Adam Bede. There are also countless Arthurs in children's literature, movies, and TV -- including The Fonz of Happy Days fame. More recently, Arthur was the son of Mr. and Mrs. Santa in the eponymous movie Arthur Christmas.
 Arthur has many notable namesakes, including playwright Arthur Miller; writer/astronomer Arthur C. Clarke; writers Arthur Conan Doyle, Arthur Rimbaud and Arthur Koestler; philosopher Arthur Schopenhauer; conductor Arthur Fiedler; and tennis great Arthur Ashe, the first African American to win the U.S. Open. Queen Victoria's seventh child was Prince Arthur.
 Arthur was a Top 20 name from at least 1880 through 1926. And in 2011, actress Selma Blair named her son Arthur Saint.

Merlin fell off the US Top 1000 half a century ago, though it ranks in the Nameberry Top 1000, which could be a harbinger of its return. About 50 baby boys were named Merlin in the US last year, and about ten girls. It is used in contemporary Germany.
