We live along the Juniata River and were supposed part of the trail North. My BIL was telling how a fellow teacher had purchased a farm and was in the process of making repairs when he discovered a false ceiling in the barn. It was a hiding place. When it was disassembled, he found a journal and a sizeable piece of one of the quilts. Left behind on purpose or just forgotten? These items were given to the Smithsonian in Washington, DC. Perfectly believable to me.
I do believe there is truth in this story. Just imagine hanging laundry/quilt on clothes line to air. It's believeable.
