I have some of the contact information for Mary as well (as do many of the Portland folkies), and hope to see her when I am in Portland next week. PM me if you need more details.
As I understand it, the stroke has mostly affected the right side of her face and her speaking centers. Aphasia, I have heard people say it is.
She is an amazing powerful woman and I am trusting that she will be able to come out of this stronger than ever.
Blessings,
Barbara
