My grandmother, Anna Urqhart, grew up on a ranch (the Dog Pound) in Alberta near Crossfield - her father was a John Urqhart. He was Glengarry Co. born and raised (Van Kleek?) and had two brothers, one William and one other. John and William went to the Caribou as young men. The other brother apparently (Albert?) was in the Union army. I do not know my grandmother's mother's name or that of her brothers and sisters but will look them up when I get home.
There was, I recall, some mixing of spouses between brothers and/or sisters as various 1st spouses died, and one of the sisters was a Margaret. (She finally ended up married to a Dr. Grant).
