Elsie is a Scottish pet form of Elizabeth, from the Hebrew Elisheva, meaning "my God is an oath". A favorite of the Victorian era, it faded in the mid-20th century and has returned with the wave of vintage nicknames such as Hattie and Millie. Elsie ranked number 1301 in 2000, entered the top 1000 in 2005 and has risen without a break from number 386 in 2015 to number 123 in 2025.
