Franciscus Yakichi
Feast: 10 September (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
At Nagasaki, Louis Yakichi and his wife Lucy were martyred with their sons Andrew and Francis: the boys and their mother were beheaded before the father, who was then burned alive.
He is one of the 205 martyrs killed in Japan for the Catholic faith between 1617 and 1632 whom Pius IX declared Blessed on 7 July 1867.
The miracles
In 1867 Pius IX approved four signs in the cause of the 205 martyrs of Japan; the source does not describe them.
Why that counted as sanctity
A boy martyred with his mother and brother.
The cause
The cause continues. No postulation address is published here yet. Favours received through this person’s intercession, and offers of help, are best sent to the religious order or congregation they belonged to, or to the diocese where the cause was opened; either will pass them to the postulation.
