I agree with Bob. John Ross seemed to be an incredibly isolated man, as we learned when he died and we discussed the collection he had amassed.

He created intellectual property that he published online. He wanted people to have access to it.

Based upon this, I'd say go ahead and publish it and credit it to John Ross, with his birth and death dates and a link to the discussion here at Mudcat. There is a photo of John in my photos here at Mudcat; he went with several of us on a ferry in Puget Sound to scatter my father's ashes. If you'd like, I can crop the original photo and send you an isolated shot. (It might take a little while to find the original, which I think is a print, but you could link to that mudcat photo in the meantime.)
