St. Cecilia went around baptizing people in the 2nd to 3rd century even after her husband and brother-in-law were executed for doing the same. She was tortured in baths of extreme temperatures by the local prefect but did not die. So an executioner tried three time to hack off her head but it refused to come off so they left her to bleed to death which took three days. In the meantime people came and collected her holy blood and were converted to Christianity.
