"Your Life is a Treasure Chest...Share it", says Kathy DeSantis on her website, Memories into Memoirs.
She offers advice on how to share those old Family Stories, and more:
You can keep the legacies alive and write one for them. In fact, one of the best things you can do for your own family and future generations of your family is to "narrate" the history of family members.
What do I mean by "narrate?" Simple -- tell the story. Write the biography. You may have all the pieces of the puzzle you need already. Other parts may not be difficult to find. But a *story* is something people who haven't caught the "genealogy bug" are far more likely to read -- and remember -- than pages and pages of your research...
She proceeds to offer an 8 part outline, or formula, to follow.
She also offers tips on getting unwilling parents, or grandparents, to open up, as well as on why you might want to write your own obituary, and how to go about it.
