I first came across St. Nuno Álvares Pereira at Whitefriars Church in Dublin, where I was attending Mass last summer at this time. I would go to Adoration as well, and one day, I noticed the Flag of St. George in the window and was intrigued by this saint.
But, there is a painting of him done in his lifetime, which is rare for a saint. He was a warrior as well as a Carmelite. I love this saint.
He was a soldier, a husband, a father and a Carmelite.
There is a fantastic blogspot dedicated to him here.

Wiki also has an article, as well as the main site of these saints.
