Your county social service office should be able to help you. You live in a climate where there is true winter, so there is always a need for quilts. People are setting up housekeeping all of the time and are in need of bedding. This need is a special problem for 18 year olds who "grow out" of foster care and get their first apartment.
If your area is very rural, the place to start may be with the sheriff's office. They see things that most people don't even know exist in a community, and they work with the social services department on a regular basis.
