Origin of the name Teresa

Cognate of Theresa. Saint Teresa of Ávila was a 16th-century Spanish nun who reformed the Carmelite monasteries and wrote several spiritual books. It was also borne by the beatified Albanian missionary Mother Teresa (1910-1997), who worked with the poor in Calcutta. She adopted the name in honour of the French saint Thérèse de Lisieux, who is the patron of missionaries.
