I've found published family histories of my family lines - the Dunns and Conners - from a distant cousin and now they are my prized possessions. This distant cousin probably never even thought that another distant cousin would have found her work, much less loved finding it. I shared some of my early work at a family reunion several years ago, but now I've found so much more it's about time to share again.
Even if you don't think anyone else in your family cares or maybe you don't have any direct descendents of your own, think again. There is always someone out there sometime that will be very grateful that you did it and was unselfish enough to share it with so-called strangers (distant cousins). It may not be Christmas when they find it, but it will be just as fun as getting a Christmas present.
