In Britain the parallel form Alice, derived via Old French, has historically been more common than Adelaide, though this form did gain some currency in the 19th century due to the popularity of the German-born wife of King William IV, for whom the city of Adelaide in Australia was named in 1836.
This name can also be given in reference to the city in Italy, as in the case of Florence Nightingale (1820-1910), who was born there to British parents. She was a nurse in military hospitals during the Crimean War and is usually considered the founder of modern nursing.
In England, Sarah came into use after the Protestant Reformation. It was consistently popular in the 20th century throughout the English-speaking world, reaching the top of the charts for England and Wales in the 1970s and 80s.
Notable bearers include Sarah Churchill (1660-1744), an influential British duchess and a close friend of Queen Anne, and the French actress Sarah Bernhardt (1844-1923).
As an English name, Zoe (sometimes with a diaeresis as Zoë) has only been in use since the 19th century. It has generally been more common among Eastern Christians (in various spellings).
