In the English-speaking world this name is more commonly given to girls. This is due to the American actress Alexis Smith (1921-1993), who began appearing in movies in the early 1940s. It got a boost in popularity in the 1980s from a character on the soap opera Dynasty.
Though in use elsewhere in Europe, the name was very rare in the English-speaking world until the 19th century, when Queen Victoria began her long rule of Britain. She was named after her mother, who was of German royalty. Many geographic areas are named after the queen, including an Australian state and a Canadian city.
