Nice looking group, Peter. I never knew any of my grandparents, much less those who were before them. At church, we have a family of 5 generations attending, the youngest being 5 or 6. Great-great grandmother (the eldest) is our church treasurer. I get some legacy-by-proxy through them and through a couple of other similar local families.
I knew three of my greatgrandparents and now I am one, twice over. My mother was able to visit with her two great-great-granddaughters a few months before she died.
