The Morrison line you posted is my maternal line.
I can clarify a couple of things there for you regarding Ethel Florine, my grandmother, and some of her children. (Link at bottom; note there are a couple of minor typos in the obituary)
Please email me if you like - I only have the 2 week trial here. I'm still trying to piece my tree together, as I'm only familiar as far back as my ggfather on my maternal side.
