Who they were
At Dobrów in Poland, the anniversary of the death of Saint Bogumilus, bishop of Gniezno, who, after leaving his episcopal see, led a hermit's life here, spending himself in an austere life.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
The Roman Martyrology remembers him on 10 June as a bishop of Gniezno who left his see to live as a hermit at Dobrów.
