That's an excellent idea, perhaps I should start with a Death Certificate. Dixon wouldn't be too far out of my way at all, as we may be flying into Chicago. I'm not optimistic that anyone would have written an obituary for Katy Tippy, as there was almost no one left by 1936, or no one that knew she was there.
I live in Swift Current, Saskatchewan. Do you have any relatives on the Canadian prairies?
I'm going to comment on your second posting separately.
