More commonly known as
Catherine of Siena, Caterina is a popular 14th century saint who was the 25th child in the family! After a mystical experience, she dedicated herself to serving the poor and sick but also became instrumental in maintaining peace during a fractious time for the Church in Rome and other Italian states. Named a Doctor of the Church for her prolific writings and influence, she died aged 33 due to a weakened body through fasting. Maybe your own Caterina would make a great peace-keeper among her own family members.
