Heather was Sean and Heather's third child and named so because when born, she had the look of her mother to her. She spent most of her life as a spinster in Montreal and helped her father and mother provide for the rest of the family (those who stayed, that is). While working as a spinster, she took some time off and traveled to her native Ireland to visit relatives, especially her younger brother Harold, who was serving as a priest in a small church in Dublin. On her return trip to Canada, Heather met the ship's captain, Aidian O'Madden. After spending most of the voyage talking to one another, Heather discovered that Aidian's boss was Brendan O'Flaherty, Heather's brother-in-law. After returning to Canada, Heather saw Aidian quite frequently and soon married him. Heather spent a majority of her later years traveling with Aidian aboard his ship and visiting America, Australia, England, France, and South Africa during their voyages. After one trip to England, Aidian's ship encountered a fierce storm just off the coast of Portugal where the ship was destroyed and all but six were lost with the ship. Heather was one of these six. She had been dragged from the ship into a lifeboat by another passenger despite the fact that she had been knocked unconscious when she hit her head on a table as she was thrown off her feet by the waves. Aidian was not so lucky. While trying to keep control of his ship, Aidian was hit by a falling masthead and was knocked both unconscious and overboard where he drowned. Heather and the rest of the survivors were picked up the next day by a British merchant ship heading for Dublin. While on board the ship, four of the six survivors died of shock or injuries, which the rescuing ship's crew could not care for. After arriving, Heather went straight for her brother's church where Harold took her in and cared for her. Heather told no one about her husband or the ship because she could not remember most of the events due to being deeply saddened by the death of her husband. Because of this, the ship was considered lost at sea, and no one learned of the ships final whereabouts.
