It was originally a term used to describe a monk who worked in the library or performed other scholarly duties. The name gained popularity during the Middle Ages and was occasionally given as a first name, but it remains quite rare today.
The name Armor has seen a resurgence in popularity from the mid-20th century to recent years, with peaks in the late 2010s and early 2020s.
