Charles HEFFORD died early 1860s on Lake Ontario, shipping between Toronto and Oswego NY; left wife Margaret (TOTTEN) and four young children in Portland, Maine, for this job; was allegedly a first mate, or just under the Captain; told wife in last letter that he might be getting his own ship; his cousin or brother, Joseph, worked ships off the Atlantic coast; these HEFFORD men were probably born in Newfoundland, Canada; Does this sound familiar to anyone?
