If you have access to the BC Archives in Victoria, I know there is information on Port Simpson. Port Simpson is just off Prince Rupert, BC, but I know many people intermarried and ended up at Port Simpson as reverend Duncan was close by at Metlakatla. At Metlakatla (a huge school and community run by Rev. Duncan) many First Nations people arrived from all over the North Coast including Haida territory.
I have done some research for family at the BC Archives and found many marriage recordings from church documents at Port Simpson. The only thing is they are not recorded in the Vital Events search, they are on microfilm if my memory serves right.
Right now I have a bad flue bug but I may have a book or two that can help, but they are in my basement and I don't feel like going down into the dungeon to collect them. I did a quick search through a book called "The Vagabond Fleet" by Peter Murray but did not see a Captain Harris. You may get some information from the Maritime Museum in Victoria:http://mmbc.bc.ca/
I found this in Hugh Armstrong's website:http://www.rootsweb.com/~canbc/1901vic_cen/1901vic.htm

Note; when I see "Port Simpson" as I do here, it rings bells, that the person is First Nations (who came from there) as it is a reservation.
Note: I see the surname "Cortsford" above and that gets me thinking. In my maternal branches of my family, a Captain Cotsford married my grandmother's aunt.I wonder if there is a connection. I will have to dig.
Kind regards; Rocky Sampson
