Hi Karen it is possible, and probable that she was born in another state. Clarke was born in Montana, I know lived in Colorado and Virginia..He was also in the military so could have met her any where I suppose. I know he was in California at least in the late 1940's until his death. Yes JACKSON is a very common name. Clarke was a white male born 1923 in Montana. He is buried in Oregon at the National Cemetery.. Thanks again Cris - Atwater California
