Ansleigh is of American origin, derived from Old English elements 'ansetl' meaning 'mansion', and 'leah' signifying 'woodland clearing'. This unique given name has been popular in recent years, particularly among parents seeking distinctive yet approachable names for their children. It gained notable attention when it was used by celebrity parents, further contributing to its rising popularity. Ansleigh is typically used as a feminine name but can also be considered unisex due to its androgynous nature. Spelling variations of this name include Annsley, Anstliegh, and Ansleighh.
"While Ansleigh was not frequently chosen as a baby name initially, it gained significant popularity around the late 1990s to mid-2000s, with a peak of 57 births in 1998 and consistently high numbers thereafter. However, there's been a recent decline since 2020."
