I totally wish that I had a lot more information about my great-grandparents. Actually, I wish that I also had listened more about the stories that my parents and grandparents had told me over the years growing up. Many of those stories have now been lost to my memory, and also to my posterity.
Luckily my father had spent some time writing down some stories that he remembered about his grandparents and parents. He was an only child, and so there is no one else to pass on that heritage of stories about my dad's family.
Click to see an online example of how this works. "Memories" are NOT long histories, nor even long stories. They could be only one paragraph long. Can you imagine if every child and grandchild of a grandfather began writing a short memory about their grandfather, there would be lots of "remembrances" of who he was, what his life may have been like, etc.
It does NOT take a long time to write a memory, 5-10" tops. Take some time to write about a family member. You may want to even write some stories about yourself and SHARE them with your family. Here is another example of a story that I wrote about being a shipboard medical officer aboard a ship, rescuing a boatload of Vietnamese refugees out in the South China Sea. After I had shared this with my posterity, two of my sons messaged me that they had never heard that story before. I had forgotten that it happened in my life years before they were born.
FamilySearch makes it so easy to create these stories and even attach photos to them. Don't just let those stories sit in FamilySearch for others to find them. SHARE them with your family members. Yep! It's very much like Facebook or other social platforms, except far more interesting, right?
