My grandfather was Myron aka Mack Knowlton. All I know is that he said he was born in Canada and that his parents were born in Nova Scotia. He married Frances Louise LeFar from Vermont, probably in the early 1900's. They resided in Helena, Arkansas, and probably operated a grocery store. He separated from Frances (I don't know if they were officially divorced) and moved from Helena, but I don't know where, possibly somewhere in Mississippi. I am searching for any information anyone might have on him and appreciate your help.
