Our families younger generation, some who are hitting their 40’s now, have no interest in the family history.
I had an aunt who died a couple of years ago at 93 who filled me in on questions I had about my grandmother and the aunts and uncles earlier lives. They’re all gone now except one aunt who is 86.
I didn’t mean preserve the history only for your family, but for everyone. Also, hopefully the children of your family’s “younger generation” will have a renewed interest in their roots - and may use the material in a school project sometime.
