Paphnutius of Thebes died in 3##.

Saint Thais is a saint of the Greek Orthodox church. According to the legend Thais was a public sinner in Egypt who was converted by St. Paphnutius, brought to a convent and enclosed in a cell. After three years of penance she was released and placed among the nuns, but lived only fourteen days more.

There is no mention of her being a patron of anyone. Penitents might pray for her intercession, I suppose, and "public sinner" is biblespeak for prostitute.
