This name appears briefly in a poem in the Black Book of Carmarthen in the form Kyrridven [1] and in a poem in the Book of Taliesin in the form Kerrituen [2]. Some theories connect her to an otherwise unattested Celtic goddess of inspiration, and suppose her name is related to Welsh cerdd "poetry".
As an English name it has been in use since the Middle Ages, originally in the form Clare, though the Latinate spelling Clara overtook it in the 19th century and became very popular. It declined through most of the 20th century (being eclipsed by the French form Claire in English-speaking countries), though it has since recovered somewhat.
This name got more popular in the early 1980s, then got a boost in 1990 when it was used by the main character in the movie Days of Thunder.
In America, this name received boosts in popularity from main characters in the movies The Jackal (1997) and Leap Year (2010).
The popularity of the name Eleanor in England during the Middle Ages was due to the fame of Eleanor of Aquitaine, as well as two queens of the following century: Eleanor of Provence, the wife of Henry III, and Eleanor of Castile, the wife of Edward I. More recently, it was borne by first lady Eleanor Roosevelt (1884-1962), the wife of American president Franklin Roosevelt.
This is also an alternate transcription of Russian Ева (see Yeva).
The name Jesus comes from a Greek transcription of the Aramaic short form יֵשׁוּעַ (Yeshu'a), which was the real name of Jesus. As an English name, Joshua has been in use since the Protestant Reformation.
The name was very popular until the 15th century in England, usually in the vernacular form Maud. Both forms were revived by the 19th century. This name appears in the popular Australian folk song Waltzing Matilda, written in 1895.
Myrddin appears in early Welsh poems, as a prophet who lives in the Caledonian Forest after being driven insane witnessing the slaughter of his king Gwenddoleu and his forces at the Battle of Arfderydd. His character seems to be based on the North Brythonic figure Lailoken, and perhaps also the Irish figure Suibhne. Geoffrey of Monmouth adapted him into Merlin in the 12th century.
This name has never been overly common in the Christian world, and it is considered typically Jewish. It was however borne by an 11th-century Hungarian king.
This was a common name in classical Greece, and, due to both the saints who carried it and the favourable meaning, it came into general use in the Christian world, being especially popular among Eastern Christians. It was however rare in Britain before the 19th century. Famous bearers include three tsars of Russia (in the Russian form Fyodor) and American president Theodore Roosevelt (1858-1919).
This name was later borne by three other English kings, as well as rulers of Scotland, Sicily (of Norman origin), the Netherlands and Prussia. Other famous bearers include William Wallace, a 13th-century Scottish hero, and William Tell, a legendary 14th-century Swiss hero (called Wilhelm in German, Guillaume in French and Guglielmo in Italian). In the literary world it was borne by dramatist William Shakespeare (1564-1616), poet William Blake (1757-1827), poet William Wordsworth (1770-1850), dramatist William Butler Yeats (1865-1939), author William Faulkner (1897-1962), and author William S. Burroughs (1914-1997).
In the American rankings (since 1880) this name has never been out of the top 20, making it one of the most consistently popular names (although it has never reached the top rank). In modern times its short form, Liam, has periodically been more popular than William itself, in the United Kingdom in the 1990s and the United States in the 2010s.
