Choi Yeong-i was a Korean Catholic laywoman and martyr born in Seoul around 1819. After marrying Carlos Cho and having one son, she remained steadfast in her religious convictions during a period of persecution. Because she refused to renounce her Christian faith, she was executed by beheading in Dangkogae. She died on February 1, 1840, and is recognized as one of the 103 Korean martyrs.
