Born to King Edwin and Queen Æthelburg, she was baptized during the early spread of Christianity in her region. After her marriage to King Oswiu, she played a significant role in the royal politics of Northumbria. Following the death of her husband, she entered religious life at the influential monastery of Whitby, where she eventually led the community as an abbess.
