Who they were
At Ferentino in the Hernican mountains, St. Ambrose the centurion. He was tortured in various ways in the persecution of Diocletian. When he passed through the fire unhurt, he was finally drowned and thus reached eternal rest.
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 Dominican Martyrology (1955) remembers him on 16 August.
