History of National Theresa Day

Theresa is a female name of Greek, Spanish and Portuguese origins. In Greek, the name possesses several meanings, the first of which is ‘from the island of Therassia,’ or ‘inhabitant of Thera,’ Thera, Thira, Therassia, or Thirassia being a Greek island now known as Santorini. Another possible meaning is ‘huntress’ or ‘hunter.’ However, it has been widely accepted that the name means ‘late summer’ in ancient Greek. The Spanish variation of the name spelled ‘Teresa’ originated from the name ‘Therasia.’

One of the earliest records of the name is traceable to the wife of Saint Paulinus of Nola during the fourth century. The name was confined to Spain and Portugal between the Middle Ages and the 16th century. It eventually spread to the other parts of the world thanks to the fame of Spanish nun Saint Teresa of Avila. Another famous woman who bore the name was the Austrian Queen Maria Teresa who inherited the domains of the Holy Roman Emperor Charles VI, her father. The French variation of the name, ‘Therese,’ received the limelight during the 19th century thanks to the life of Saint Therese of Lisieux, who wrote a touching account of her life titled “The Story of A Soul,” which makes her one of the most famous saints of modern times.
