Angela Merici, whose Company of St. Ursula was formed of lay women, living at home and not in convents, not cloistered, not in habits, not under the control of men in the church...until after she died and her community was forced to change to a monastic, cloistered, habitted community of nuns. AND they weren't a teaching community from the start--that's part of the myth. The ministry was more one of presence and serving where needed. Teaching came later. 
I'd include Angela, who believed women could lead their own lives and dedication to Christ.
