I just recently went through a suitcase full of pictures my grandmother had. Somehow I got elected to figure out who the people were and try and return the pictures to as many as I could find. Some were easy, cousins, etc. but some were people who died many years ago and left no family. While going through them I came across a memorium from a funeral or two and lo and behold some kind person had taken the trouble to list full names of the deceased's children and their spouses. Without these I might never have uncovered who these people were or how they fit in the family. So, in addition to writing a full history on the back of all our pictures we also need to think about giving a thorough accounting for all descendants of the deceased. LOL.
