I would like to highlight one of the saints, St. Margaret Ball. Here is a link on these martyrs for your perusal. St. Margaret was betrayed by her son and husband, a cruel event, marking her as a martyr before her death in prison.
Born Margaret Bermingham about 1515 in Skreen, Co Meath, she married Bartholomew Ball, a prosperous merchant in Dublin. Her eldest son, Walter, however, became a Protestant and an opponent of the Catholic faith. Margaret provided 'safe houses' for bishops and priests passing through Dublin and would invite Walter to dine with them, hoping for his re-conversion.
Walter was elected Mayor of Dublin. He had his mother arrested and drawn through the streets on a wooden hurdle, as she could no longer walk, to Dublin Castle. Here she remained imprisoned for the rest of her life. If she had renounced her faith she could have returned home, but she refused and died in prison aged 70 in 1584. The chapel-of-ease at Santry in Larkhill parish was named in her honour.
