I just happened upon a very relevant quote by Michael Crichton, and added one important word to it:
“If you don’t know family history, you don’t know anything. You’re a leaf that doesn’t know it is part of a tree.”
So true. You are part of a huge family tree with hundreds of branches. Wouldn’t it be nice to record the stories of your own special branch on that ancient tree? If not for you, then for the new leaves that form in years to come. Let them realize that they are a part of something special, that they belong to the history of your family.
