Protestants became even more fearful when James's wife, Mary of Modena, gave birth to a son–James Francis Edward–in June 1688. They were afraid because the son, unlike Mary and Anne, would be raised a Roman Catholic. Some said that the boy had been secretly carried into the Queen's room in a bed-warming pan instead of her stillborn baby. There was no strong proof to support this story, but Mary publicly doubted the boy's legitimacy. She sent a list of suspicious questions to her sister, Anne, about the boy's birth.
