This name is borne by a Jewish woman in Walter Scott's novel Ivanhoe (1819), as well as the title character (who is deceased and unseen) in Daphne du Maurier's novel Rebecca (1938).
In the United States this form was more popular than the full form Elizabeth from 1958 to 1978, and was in fact the top ranked American name between 1962 and 1969.
Although this name was used by Jews in the Middle Ages, it was not typical as an English Christian name until after the Protestant Reformation, being common among the Puritans.
The English names Jacob and James derive from the same source, with James coming from Latin Iacomus, a later variant of the Latin New Testament form Iacobus. Unlike English, many languages do not have separate spellings for the two names.
In England, Jacob was mainly regarded as a Jewish name during the Middle Ages [1], though the variant James was used among Christians. Jacob came into general use as a Christian name after the Protestant Reformation. In America, although already moderately common, it steadily grew in popularity from the early 1970s to the end of the 1990s, becoming the top ranked name from 1999 to 2012.
A famous bearer was Jacob Grimm (1785-1863), the German linguist and writer who was, with his brother Wilhelm, the author of Grimm's Fairy Tales.
This name was moderately popular through most of the 20th century, and became very popular around the turn of the 21st century. It was the highest ranked name for girls in the United States from 1996 to 2007, attaining similar levels in other English-speaking countries around the same time.
Famous bearers include the British author Emily Brontë (1818-1848), known for the novel Wuthering Heights, and the American poet Emily Dickinson (1830-1886).
