As an English name, Benjamin came into general use after the Protestant Reformation. A famous bearer was Benjamin Franklin (1706-1790), an American statesman, inventor, scientist and philosopher.
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-).
