I have hundreds of photos and slides of parents, grandparents even great grandparents. But I am an only child, have no children with present or previous(deceased) wife so no one who wants any of it. Current wife is only child also. I left a note in my will, that they can either dumpster it all or throw it in my coffin and I'll take it with me! Maybe some future archeologist with get a kick out of it!
Remember they used to say "digital will last forever" So what if no one keeps it on a current media.
