According to wikipedia:
Mary of Egypt (ca. 344 – ca. 421) is revered as the patron saint of penitents, most particularly in the Eastern Orthodox, Oriental Orthodox, and Eastern Catholic churches, as well as in the Roman Catholic and (unofficially) Anglican churches.I think her life alone is an interesting read in and of itself. I know we have our doubts of the story but stop for a while and read how the story goes.
Then we have the trio of girls: Agape, Chionia, and Irene
Now these three saints are hardcore. Read up and you will be amazed.
I also came up the an article about the dessert mothers. Saints are an interesting bunch of people
