According to an item in the Glasgow Herald, 27 Oct 1871, the Clutha (no "Jane") was lost (along with the Cynthia) on the island of Anticosti, in the Gulf of St. Lawrence.
No mention of the master or crew - described as "1060 tons, built in Quebec in 1855, and owned by Mr W Wright of Shields.
I can also see an 1845 reference to the "Clutha, Jane" (need to check further).
