Do you have your family history recorded? If not, go to Family Tree Magazine and print out the family group sheet and family tree. It is really easy to fill in your information when you have family to ask, but if you wait too long you lose the important things, like the family stories!
Listening to the Great Aunts and Uncles telling on each other was a hoot! I was 30 years old and 2 years later they were all gone, so don't wait! It costs nothing to start and the rewards are life-long.
