Hello, It's been many years since you posted this so I'm not sure if you're still looking, but D. Leslie Loree was my great grandfather and his son George Loree was my grandfather. There were a few books done up about the area. One was called Mosquito Creek Roundup Nanton-Parkland. I have a copy of this at home.
My Great Aunt Jane Loree (Wilson) did a full history of the Wilsons as well. My grandmother Dorcas Loree (Wilson) was married to George Loree, D. Leslie Loree's son. Jane was married to George Loree's cousin, Gerald Loree.
I also have some family in Alberta that knows a lot more about this than I, so please be in touch if you want any further information on the George Loree branch of the family.
