[1] Their memorial in the current General Roman Calendar is on November 24 as Saint Andrew Dung-Lac and Companions (Vietnamese: Anrê Dũng-Lạc và các bạn tử đạo), although many of these saints have a second memorial, having been beatified and inscribed on the local calendar prior to the canonization of the group.

[2] John Paul II decided to canonize both those whose names are known and unknown, giving them a single feast day.

[6] The letters and example of Théophane Vénard inspired the young Saint Thérèse of Lisieux to volunteer for the Carmelite nunnery at Hanoi, though she ultimately contracted tuberculosis and could not go.

During the turmoil, the missions revived, however, as a result of cooperation between the French Vicar Apostolic Pigneaux de Behaine and Nguyen Anh.

[11] The bishop Dominic Henares was found in Giao Thuy district of Nam Dinh (later executed); the villagers and soldiers that participated in his arrest were also greatly rewarded (about 3 kg of silver distributed).

In July 1838, a demoted governor attempting to win back his place did so successfully by capturing the priest Father Dang Dinh Vien in Yen Dung, Bac Ninh province.
