for Santa Cecilia
The church of Santa Cecilia is in Trastevere. It was first built in 5th century. She is killed because she kept converting people to Christianity, including her husband and as a result the marriage was not consummated. It strikes me that she and other saints are wilful virgins. Her husband, Valerianus, was martyred too.
For more on Santa Cecilia, Barbara Grizzuti Harrison, in her Italian Days (1989) writes about her (pp. 248-249).
