Everyone loves stories...and stories belonging to our particular families have a different charm altogether...stories of the lives and times of our grandparents, or great-great-grandparents, are fascinating, and make lineage come alive and real...
It's not so much roosting on your heritage, or being ashamed of the doings of your ancestors, or basking in the glories of deeds done by your family years and centuries ago...
It is just a feeling of continuity, and you are adding to it...
