I have a impulsive idea but I'm relectent to do it it's a book called stories of my Grandparents and would be

I think it is an excellent idea. I wish I had done that when I was younger. Our grandparents lived in an entirely different world than we know. French fries were not even invented when my grandparents were young and ketchup made from tomatoes was almost unheard of. I would read it. It would be a great legacy to leave your family.

This is a little off of the path of what you're doing, but I would recommed reading "Angle Of Repose" by Wallace Stegner. It won the Pulitzer Prize 30 years ago and is about an invalid researching his grandparent's lives. It's based on actual people in the 1800's. You might find a way of telling your grandparents lives.

i would write it and give it out to the family..your family is the one that would more than likely read something like this...it would be a great gift for them
