I donate through my guild - even if you're too far away from a guild to join up, you can probably email the local one and get a list of charities. Some charities have specific needs/wants for the quilt construction, others will take whatever they can get.
Charities for women & children go through a lot of quilts, and some animal shelters will take them too.
Our guild had a speaker come in recently from the local women's shelter that we donate to, and by the time she was done telling us how much these quilts matter to these women there wasn't a dry eye in the room!! So it's really sweet of you to think to sew and donate quilts with your inheritance, I'm sure your aunt is beaming with pride and joy wherever she is.
