I use the on-line guest book often when it is someone I knew or a family member of someone I knew from my home town. I moved away over forty years ago and I do not have current addresses, I hope it gives the family some comfort to know that someone from their past cared enough to say something positive. I was very moved, when my father died, that people who had been neighbors before I was born (and at that time I was in my late 30's) reached out to the family. The only negative has been, I was contacted be an old boyfriend.
