My great grandfather and great grandmother Kinnerk, sailed from Sligo, Ireland to Quebec, Canada in May 1847. After leaving Ile Grosse in Canada the ship ran into weather going north to the mouth of the Saint Lawrence River. The ship wrecked about four miles east of Cap Rosier. Many of the Irish drowned. I have found the shipwreck and the ship's name but nothing else. Can you help me? Dan Pyne
