You might want to hand write the history of each quilt onto muslin, then hand stitch it to the back of the quilt. That way it is "with" the quilt and won't get separated. Whoever ends up with them will certainly appreciate getting the information with the quilt. You are very lucky to have these. I have only one tiny crazy quilt from one grandmother, and a stuffed cat sewn from a piece of quilt made by my other grandmother.
