It depends entirely on your group's bylaws. How do they define membership in your group? Is it anyone who pays dues, or is it limited to anyone who has a child in the school? And do your bylaws list any further limitation on who can hold office (ie must have a child in the school)? If your bylaws don't have any of those limits, then it's perfectly fine for the grandmother of the former student to be president.
