Teresia is a feminine given name of Latin origin, derived from the Latin word "teresa," which means 'to harvest' or 'to gather'. It is often associated with the Latin phrase "Deus te gerat" meaning 'May God protect you'. The name Teresia gained popularity during the Middle Ages in Europe, particularly in Italy and Spain. It was typically given to daughters of wealthy families as a symbol of their protection and prosperity. Today, Teresia is still used as a given name, but it is less common than it once was, contributing to its unique and distinctive sound. Some famous individuals with this name include Saint Teresa of Ávila, a prominent Spanish nun and theologian, and Teresia Krantz, a Swedish actress known for her roles in various films and television shows.
The name Teresia experienced a significant rise in popularity between the late 1940s and mid-1950s, with the highest number of births recorded in 1956 (68 births). However, it declined thereafter, with fewer than ten births per year from the early 1970s onwards. The name has been quite uncommon since then, with only sporadic occurrences up until 1994 (seven births). Overall, there were a total of 1,133 births named Teresia over this period.
