Albertina Berkenbrock was a Brazilian Catholic girl born in 1919 who lived in Imaruí. A member of a large, religious farming family, she was known for her devotion to the faith and for teaching catechism to local children. In 1931, she was killed while resisting an attempted rape by a man who worked for her father. Because she died defending her chastity, the Catholic Church recognized her as a martyr, eventually leading to her formal recognition as a blessed.
