Hi, thanks Barbara & Frank! I do know where he died, and I've found a bunch of census records after the point he moves to Fall River, Mass in 1880 and marries in 82 (which rules out the other possible J F Richards listed), and then moves to Brockton, Mass where he spent most of the rest of his life. I dont have a death cert yet though, but I know he was a barber. None of those records have yielded his parent's names yet though. I think you are right about trying to find a newspaper obit, and now that I think of it- one of his own sons is listed as a writer for a newspaper in all of the census records I've seen, (my 2nd great uncle) I wonder if he wrote an obit for his own father? He was Raymond Joseph Richards and lived around Brockton, Mass also. I'll try to track down some obits next.
At least I know his birthday positively now, and Port of Quebec too, (although I'm finding there may be a bit of a language barrier). Thanks again guys!
