Martha Hennessy is the seventh grandchild of Dorothy Day. She is a retired occupational therapist with nine grandchildren of her own. Martha divides her time between family and farming in Vermont, and volunteering at Maryhouse Catholic Worker in New York City, the same house where her grandmother passed away in 1980. There, the community continues to practice the works of mercy serving food to the homeless, as well as providing showers, a clothing room, and phone access.
