BArbara, I am sure that your local Historical Society would either love to have them or would know the best place to donate them. I was part of a state wide quilt documentation program here in Maryland in the late 80s. It was co-sponsored by the then Extension Homemakers and the DAR musuem in Washington, DC. Our county documented over 600 quilts. We took pictures of them hanging on a frame both of the entire quilt and some close ups of blocks or motifs. We attached a label to the back of each of them with a reference number from the documentation that would link them to the information and pictures than stored by the Historical Society. We had textile experts come in from the DAR and other institutions to examine them and give their opinions of the age, workmenship, present condition and value of each quilt. We also helped the persons presenting the quilts fill out a detailed questionare concerning the history of the quilt and it's maker along with any legends or family stories connected. The quilt owners got copies of everything including the experts comments and photos if they so desired. Our local historical society was thrilled when several of the quilts were donated to their collection.
The historical society would also be a great place to get contact informaiton for textile experts or appraisers in your area.
We would also like it if you shared pictures of the quilts with us.
