You may recall Ann B. Davis for her role as "Alice" on The Brady Bunch or, if you're closer to my age, "Schultzy" on The Bob Cummings Show. However, she was also a devout Episcopalian who lived half of her life in a community of like-minded people dedicated to prayer and good works.
Her obituary may be found here. An interesting article about her may be found here: "How Ann B. Davis changed my life".
