As an English name, Hannah was not regularly used until after the Protestant Reformation, unlike the vernacular forms Anne and Ann and the Latin form Anna, which were used from the late Middle Ages. In the last half of the 20th century Hannah surged in popularity and neared the top of the name rankings for both the United States and the United Kingdom.
