The name was mainly confined to Spain and Portugal during the Middle Ages. After the 16th century it was spread to other parts of the Christian world, due to the fame of the Spanish nun and reformer Saint Teresa of Ávila. Another famous bearer was the Austrian Habsburg queen Maria Theresa (1717-1780), who inherited the domains of her father, the Holy Roman emperor Charles VI, beginning the War of the Austrian Succession.
This is the name of several New Testament characters, most importantly Mary the mother of Jesus. According to the gospels, Jesus was conceived in her by the Holy Spirit while she remained a virgin. This name was also borne by Mary Magdalene, a woman cured of demons by Jesus. She became one of his followers and later witnessed his crucifixion and resurrection.
Due to the Virgin Mary this name has been very popular in the Christian world, though at certain times in some cultures it has been considered too holy for everyday use. In England it has been used since the 12th century, and it has been among the most common feminine names since the 16th century. In the United States in 1880 it was given more than twice as often as the next most popular name for girls (Anna). It remained in the top rank in America until 1946 when it was bumped to second (by Linda). Although it regained the top spot for a few more years in the 1950s it was already falling in usage, and has since dropped out of the top 100 names.
This name has been borne by two queens of England, as well as a queen of Scotland, Mary Queen of Scots. Another notable bearer was Mary Shelley (1797-1851), the author of Frankenstein. A famous fictional character by this name is Mary Poppins from the children's books by P. L. Travers, first published in 1934.
The Latinized form of this name, Maria, is also used in English as well as in several other languages.
The French theologian Jean Calvin (1509-1564) and the philosophers Jean-Jacques Rousseau (1712-1778) and Jean-Paul Sartre (1905-1980) are well-known bearers of this name. It was also borne by the German-French Dadaist artist Jean Arp (1886-1966).
Heinrich was popular among continental royalty, being the name of seven German kings, starting with the 10th-century Henry I the Fowler (the first of the Saxon kings), and four French kings. In France it was usually rendered Henri from the Latin form Henricus.
The Normans introduced the French form to England, and it was subsequently used by eight kings, ending with the infamous Henry VIII in the 16th century. During the later Middle Ages it was fairly popular, and was generally rendered as Harry or Herry in English pronunciation. Notable bearers include arctic naval explorer Henry Hudson (1570-1611), American-British novelist Henry James (1843-1916), American automobile manufacturer Henry Ford (1863-1947), and American actor Henry Fonda (1905-1982).
Hector has occasionally been used as a given name since the Middle Ages, probably because of the noble character of the classical hero. It has been historically common in Scotland, where it was used as an Anglicized form of Eachann.
