I don't know how to repair the quilt to use it again. Someone else might. I think it may likely be a treasured keepsake. My sister received a quilt made by our great grandmother. It was tattered from age and wear, beyond use and useful restoration. My sister spent a lot of time finding similar fabrics from reproduction collections and reproduced the quilt, even hand quilting it in the same pattern. It isn't the same quilt made by my great grandmother's hands, but my sister enjoyed the journey, somewhat following in her path and her quilt will probably be used over many years like the original.
