Thanks for the eyeball, guys. Likely I bat .500 on this. Regenstreif is a reliable and excellent source. On the other hand, I took this from the "Calgary Herald" within a few days of the death. Hemsworth was well known to them. I don't find the article today (they only keep obits online 30 days) but The Canadian Encyclopedia agrees with the 19th.

That don't make it absolutely so - I take no bar bets on these things. I don't think I'll find a source that will give 1902, though.
