Yes, your grandchildren WILL appreciate your stories - someday - but your great grandchildren will appreciate them even more.  How much would you pay to have a copy of the original story your 2nd great grandmother wrote about meeting her husband?  How much would you pay for the original story written by your passenger on the Mayflower?  I remember when I found an original letter written by my grandmother to her daughter, my mother.  I was thrilled!  My grandmother was literate!  These were poor farmers from poor families and poor ancestors.  There was no need for a woman at that time to learn how to read and write.  My female ancestors needed to know how to farm, make clothes, cook from what was available, and cure without medical professionals or strange chemicals.

I can't imagine what I would give for a video interview with my 2nd great grandmother who - by all accounts - was a feminist who divorced  her cheating husband in the 19th Century. Even Hillary didn't do that!  

For anyone with no direct descendants, you have family and you will have family in 100 years.  Your family is a lot more than what comes out of your womb.  They will want to know.  Look forward by looking back and recording what you see.

I have now proven my descent from 5 Mayflower passengers: Stephen Hopkins, John Howland (the boy who fell off the Mayflower and was rescued), his eventual wife Elizabeth Tilley, and her parents, John Tilley and Joan (Hurst) Tilley. Having these records in the archives of a national organization ensures they will be preserved for future generations.  I urge everyone to share their lineage with local, state, and national organizations that will preserve those records.
