[14] The mortification of the Bostonians at the failure of this expedition was extreme. So confident of success were they that preparations were made for a public rejoicing on the anticipated capture of Port Royal. The young baron St. Castin was wounded in the defence of Port Royal. His conduct in leading the defenders on several critical occasions was characterized by such dash and intrepidity that Governor Subercase in describing the siege wrote to the French minister at Versailles that if it had not been for the presence of the Baron St. Castin he knew not what would have been the result. See Murdoch's Hist. Nova Scotia, vol. I., p. 289. A few years later the Marquis de Vaudreuil entrusted to St. Castin the command of Acadia. After the treaty of Utrecht he retired to his ancestral residence on the banks of the Penobscot, where he lived on amicable terms with the English and kept the Penobscot Indians from making encroachments on their neighbors. His sister, Ursule de St. Castin, married his wife's brother, a son of Louis d'Amours, a circumstance of interest not only as being a double marriage between the families of St. Castin and d'Amours, but also from the fact that the familiar titles of the d'Amours family seem to have been retained in this, the oldest branch of their family. In proof of this fact, the distinguished Acadian genealogist, Placid P. Gaudet, has shown that among the Acadians residing at the Islands of St. Pierre and Miquelon in 1767 (according to the census of that year), were Ursule de St. Castin, widow of the only son of Louis d'Amours, then 71 year of age, who resided with her son Joseph d'Amours, deChauffour, and his family. Joseph d'Amours was at that time 49 years of age, and his wife, Genevieve Roy, 44 years of age. They had seven children and the oldest sons were Joseph d'Amours, aged 19 years; Paul d'Amours de Freneuse, aged 16 years, and Louis d'Amours de Clignancourt, aged 13 years. As the father himself retained the title of de Chauffours it is evident that on his decease it would fall to his oldest son, Joseph. Marie d'Amours, sister of the young Baroness de St. Castin, married Pierre de Morpain, the commander of a privateer of St. Domingo. It chanced that he had just brought a ship load of provisions to Port Royal when it was attacked in 1707, and he was able to render good service in its defence. Two years afterwards he was again at Port Royal and in the course of a ten days' cruise took nine prizes and destroyed four more vessels. Being attacked by a coast-guard ship of Boston a furious engagement ensued in which the English captain was killed with one hundred of his men and his vessel made a prize and taken to Port Royal. The commander, Subercase, highly commended Morpain's bravery and persuaded him to remain at Port Royal where, on August 13, 1709, he married Marie d'Amours de Chauffours.
