Here's a suggestion- The first page is of them when they married and one of them now. Then each of the kids have a page with pictures with them thru the years, a page with pictures of spouse and then each grandchild have a page. (Scan it so everybody has a copy of the pictures.) For my parents, we took pictures at the event of the people that came and tried to get them in family groups. For example, the next door neighbors with their 2 grown children and families. The page had neighbors, the neighbors with their children and grandkids and then each of the children with their family. Having it like that helped mom and dad remember what kid went with who.
