What is a granddaughter’s view of someone widely regarded as a saint? Kate Hennessy is in a privil­eged position to answer the question – her mother was Tamar Hennessy, the only child of Dorothy Day, founder of the Catholic Worker movement.

Pope Francis signalled his support for such recognition when he named Dorothy Day as one of four Americans he especially admired.
