This name was borne by the heroine of Lewis Carroll's novels Alice's Adventures in Wonderland (1865) and Through the Looking Glass (1871).
This is one of the few Old English names to be used throughout Europe (in various spellings). A famous bearer was the British composer Edward Elgar (1857-1934). It was also used by author Charlotte Brontë for the character Edward Rochester, the main love interest of the title character in her novel Jane Eyre (1847).
In the United States this form was much less common than Isabel until the early 1990s, when it began rapidly rising in popularity. It reached a peak in 2009 and 2010, when it was the most popular name for girls in America, an astounding rise over only 20 years.
A famous bearer is the Italian actress Isabella Rossellini (1952-).
This name also appears in the New Testament, belonging to man who sheltered Paul and Silas. In his case, it may represent a Hellenized form of a Hebrew name. It was not used in England until after the Protestant Reformation.
