This name has been used in the English-speaking world since the Protestant Reformation. In America it received a boost in popularity after the birth of Esther Cleveland (1893-1980), the daughter of President Grover Cleveland [1].
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.
In England the name became rare after the Middle Ages, but it was revived in the 19th century, more commonly in the spelling Beatrice. Famous bearers include the British author and illustrator Beatrix Potter (1866-1943), the creator of Peter Rabbit, and Queen Beatrix of the Netherlands (1938-).
