I have had the great fortune of relatives who documented their research before I became interested. While some might say this has kept me from doing my own research, I feel I have been able to research the information (to verify information and see what might have been missed), but have been extremely happy to have copies of pictures taken of the family five generations back and details no longer available, like which family member accomplished which chores and small details they remembered about parents and siblings. Had these documents/pictures not been retained (and names placed on them) by previous generations, a huge amount of our history would have been lost. There are also Civil War letters (from the US) and other documents that have been fascinating to read. However, my recommendation is to find a family member who cares, even if they are distant, and provide the information to them. One of my greatest sources is a distant cousin. Once I asked her where she found out so much information and she told me that my grandmother had provided it to her before I was old enough to care. Had my grandmother not shared the information, it would not have been there for me when I decided to look for it. (An aunt decided it was all worthless when she died and sold or burned the stuff that was left.) Finally, other family members have created books from their histories and provided it to the family. That is what I am doing as well. While most of the family does not care about "John begat Sam begat Susan", when you can tell the story about William's father dying young and the family selling everything they owned to purchase a one way ticket to America, hoping they would make it on their arrival, everyone becomes much more intrigued. Now many family members want copies of my updates when we get together. This year, my cousin's oldest son even asked if I could teach him how to conduct the research. While close relatives may not be extremely interested, if you put the information out to the family, it will pique someone's interest.
