That reminds me. I have two attic stories. One, when one of my brothers was in law school (which was in the same town my grandfather was born and died in) one of his friends asked if he was related to my grandfather, who had died a long time ago, and when he found out, he gave my brother a box of stuff that had been found in the attic when his parents bought the house. It was a bunch of memoribillia of my grandfather. I don't know if they ever really found out why the stuff was in the attic.
And last year I found a "new" relative. He said a couple years ago he went back to the town that his father, grandparents, and great-grandparents had grown up in. His dad had told him that he remembered stuff being in left in the attic of the family home, so he knocked on the door. He said the people were wonderful, but they had remodeled about a year ago and thrown everything out. Yikes. What timing.
