Elvy is a unisex given name of Scandinavian origin, derived from the Old Norse word 'álfr', meaning elf. It was initially used more frequently as a male name but has gained popularity among females in recent years. The name Elvy was popularized by the Swedish actress Elvy Lindgren, who was known for her roles in silent films during the early 20th century.
Elvy was a relatively uncommon name throughout much of the 20th century, with a notable peak in usage between 1916 and 1925, when it appeared at least once every year except for 1921. After a gap of over seven decades, the name began to reappear more frequently starting from 2015, suggesting a possible resurgence or renewed interest in recent years.
