Yep, it's true. It has happened. I just turned 19 and I am actively involved in Family History. Too often our generation procrastinates this great work or puts it on others' shoulders, but there is much we can be doing now. It is our responsibility just as much, if not more, than the older generations.
My grandmother, Isabelle Lamoreaux Holladay Cluff, was an amazing genealogist. She always has been since she was my age. Well, she passed away last June. I had been actively Indexing (you can check that out here) since I was 13, but I had never really been into any hardcore family history work. Well, that has changed. I have felt a renewed vigor to search out my ancestors and find my kindred dead. I have felt so blessed and close to my grandmother as I have done this work. Genealogy was her love and her greatest legacy; I intend to carry that on.
