I have no advice about what to do specifically about the quilts, but these resources sound fantastic. I'm chirping up to say that something that old with that much history that you've discovered is worth trying to preserve in whatever way possible. Yes, I'm the known packrat, but these sound like something that contribute to the definition of your family culture. Try your best to preserve what you can!
