Re the quilts that were made for granchildren and kept by the daughterin law.
Consider charging her with theft! I would definitley speak to a lawyer,
When you do, have some idea of what the quilts are worth if bought on the open market or if you had to have them made. Take pictures of the quilts with you to the lawyer if you have them.
As they were a gift to someone else, the quilts are not hers to keep.
