Hi Sherri,
My name is Barbara Todd, maiden name Mann and Edna was my mother who passed away in 1969 at the age of 49. About 16 years ago or so, I traveled to Edmonton to visit one of my father's brothers and while I was there, visited South Cooking Lake where mom was born. I was fortunate to come across a hard cover book depicting the last 100 years of S. Cooking Lake. There is a section for Christopher Chadwick and some of his children and their wives but not a great deal. Very little is mentioned regarding Leslie Chadwick except for the children he had with his last wife. My grandmother's name is not there but the children's names are. Clara May, Annie, Nellie (who died young), Edna (my mom), Elsie (mom's twin sister) then known as Janet, Hannah and Arthur (twins). I would be happy to hear from you.
