Jean Lidderdale Campbell is the first daughter of George Arthur Lidderdale, son of Arthur Edwin. Jean is therefore the first cousin of Shirley, Leonard, Lyle, and Michael.

Jean is a major contributor to this memorial, because her work on uncovering the Lidderdale genealogy led to results none of us had ever seen. She is seated in the center of the front row (in the darker pink), surrounded by her family (more cousins).
