Agatha was married at a young age, about 12 or 13 years old, but her husband was too poor to care for her, so she lived with her relatives.

Nine of the Danggogae martyrs, including St. Agatha, were canonized by Pope John Paul II in 1984, when he canonized 103 martyrs and French missionaries killed during the waves of persecutions in Korea. There is a shrine dedicated to the martyrs at Danggogae, which honors the third-highest number of martyred saints in Korea.
