Personally, I'd prefer to have a legacy with my family, not some digital screed.
For instance, I can see my grandkids, in the kitchen with their grandkids, saying, "Here's the pancake recipe I used to make with my grandpa, WBill. Lemme tell you about the time he and I....."
If that happens, I'd consider myself a success.
I hear you but it still gets forgotten with time.
I bet only 1 in 1,000 knows the name of his/her great, great, great grandfather/mother.
Go back a few more generations and the odds are far less.
Through Ancestry.com, I’ve been able to place my mother’s side of the family to the year 1,000 AD, and the family here came to America in 1632. BUT... I don’t know their nicknames, that is, what they liked to be called, their personalities, thoughts, foibles and triumphs... Just names on paper (or digital bits).
For my Dad, his parents came here in 1917, and he can only name his paternal Grandparents. Doesn’t even know his mother’s parents name. His mom was a Jew from the Russian empire, who got pogromed several times before escaping to Britain, met my Grandfather, another refuge from the Great War, and they left for America in December 1916. got torpedoed by a U-Boat off Newfoundland, but the ship survived and eventually made it to New York.
