Most recent beatified model of purity.

Bl. Albertina Berkenbrock (1919-1931)
.
From the Holy See website:
.
"Albertina Berkenbrock was born on 11 April 1919 in São Luís, Imaruí, Santa Catarina, Brazil. She was baptized on 25 May 1919 and confirmed on 9 March 1925. She made her First Holy Communion on 16 August 1928.
.
Albertina grew up in a devout family. She willingly helped her parents at home and on the land. At an early age she learned to pray with deep devotion and was strong in the practice of her Catholic faith. She spoke of her First Communion Day as the most beautiful day of her life and had special devotion to Our Lady and to St Aloysius Gonzaga, a model of purity and the Patron Saint of São Luís.
.
At school Albertina was a model for her peers and a cause of admiration to adults. Her teachers especially praised her spirituality and morals, superior to children of her age. She was a diligent student who knew her Catechism and kept God's Commandments.
.
At home, when her brothers teased and taunted her, as siblings do, she would not retaliate. With her Christian upbringing, even the childhood games she played reflected her deep religious sense. She played happily with the poorest children and shared her bread with them.
.
At home, she was especially loving to the children of an employee of her father; while unknown to her, that man would become her future assassin.
.
One day when Albertina was searching for a runaway bullock she came across Maneco loading beans into his cart. When she asked him if he had seen the bullock he pointed in the wrong direction to entice her to a place where he could satisfy his lust without attracting attention.
.
Innocently, Albertina followed Maneco's directions and came to a wooded area. On hearing twigs cracking she turned, thinking it was the bullock, and found herself face to face with Maneco. She was petrified.
.
He informed her of his intentions but she firmly refused him. Albertina fought hard for her virtue. Even when he threw her to the ground, she did her best to cover herself. Furious at having been morally defeated by the young girl, Maneco grasped her by the hair and slit her throat with a knife." - Finish reading here.
