English: Saint Agnes Lê Thi Than was born in 1781 in Bai Dien village (Bai Den or Gia Mieu), Yen Dinh district, Thanh Hoa province. Her parents were from a religious background and the family was well-off, but they did not have a son to carry on the family line, so their father married a second wife, forcing Ms. Thanh's mother to have two daughters, Thanh (12 years old) and Thuoc (10 years old). went to settle down in Dong village, Phuc Nhac commune, Ninh Binh province.

At the age of seventeen, Ms. Thanh married Mr. Nguyen Van Nhat, giving birth to two sons and four daughters. According to local custom, the villagers use the name of their first-born son to call their parents, so Mrs. Thanh is also called Mrs. De.

The couple cared about nurturing and educating their children in faith. In particular, Mrs. De greatly respects those who dedicate themselves to God, especially missionaries and native priests. Their family was always ready to welcome missionaries to stay during times of persecution.

On the morning of the Great Resurrection of the Lord, April 14, 1841, De, who followed Father Thanh's side, wanted to make a merit and wanted a reward, and secretly reported the shelter of the southwestern leaders to Governor Trinh Quang Khanh. Missionary priest Jean Paul Galy Carles - Ly was taken by tycoon Co to Ms. De's garden, hiding in a dry ditch next to a bamboo bush, covered by straw. But the soldiers saw the figure running away so they tried their best to search and eventually arrested the father. Mrs. De, the homeowner, was also arrested for hiding the religious leader in the house. Boss Co, Ms. De and eight other people were shackled and taken to Nam Dinh prison. Because the shackle was too heavy, Ms. De collapsed many times on the road.

At the public hall, Governor Trinh Quang Khanh's sweet admonitions, corporal torture, beatings until his bones was broken, releasing poisonous snakes down his pants legs... could not shake Mrs. De's staunch faith.

When visiting her mother, Ms. Nguyen Thi Nu sobbed when she saw her mother's shirt stained with blood, but Mrs. De lovingly comforted her: "Don't cry, I'm wearing a rose shirt, I'm happy to suffer because Jesus, why are you crying?” On another visit, Mrs. De reminded her: "Go home and pass on my mother's message to your brothers and sisters. Remember to take care of the housework, keep the religion fervently, pray morning and night, offer Mass, and pray for mother to carry the Saint." Price to the end. Soon, we will reunite in Heaven."

In addition to torture and poor diet, Ms. De also suffered from dysentery. Despite the dedicated nuns taking care of her, Ms. De's strength became weaker and weaker and she rested in God on the night of July 12, 1841 in prison, during the reign of King Thieu Tri. According to regulations, soldiers burned her toes to confirm that the death row prisoner had passed away. Her body was buried at Nam Mau execution ground, and six months later was reburied by the faithful at Phuc Nhac church.

Saint Anê Le Thi Thanh (Dê) was beatified on May 2, 1909 and canonized on June 19, 1988.
