Elizabeth is a name of Hebrew origin and means "God is my oath." It was first used by the biblical Queen Elizabeth I of England in the 16th century. The name has been popular among royal families for centuries, with notable bearers including Elizabeth I herself, as well as Elizabeth II, who was the longest-reigning monarch in British history. Despite its regal associations, however, Elizabeth is also a common name among non-royal individuals and remains a popular choice today.
"The name Elizabeth was quite popular in 1987 and 1988 with 5 births each year, but there was a slight dip in 1989 before it rebounded to 5 births again in 1990, making the total number of babies named Elizabeth over these four years 15."
