If you have children or nephews and nieces I’m sure they will benefit from the effort you are putting in, as well as the benefit you receive.

I remember being very impressed when reading a biography somewhere online of Alexander Grothendeick, that it was a family tradition to keep biographies on ancestors, so he had this knowledge as well. I know very little of my great grandparents, and nothing beyond them, which I am sure is common in the United States.
