It can get quite profound. I researched quite a bit of my family history a few years ago until other events overtook me. I found that reading about their lives and community brought me closer to my ancestors and I like to think that somewhere down the line my descendants will discover things about me and my life and how it might have affected their circumstances. I know, for example, that my parents and their generation had to go without so that I could enjoy the beneifts and pass some of them on through my children.
