Nancy Willich, Ann Guyer, and Margaret Byers, the sister authors of "Your Mother Has Alzheimer's" (Three daughters answer their father's call.) were born and raised in Wisconsin. After living throughout the country (Virginia, Florida, Colorado, Texas, California), Margaret/Peggy and Nancy have returned to the Badger State and share a home on the Chain O' Lakes. Ann lives in Northfield, Minnesota. Mothers of seven adult children and grandmothers of seventeen, the sisters came together to write the story of their family's journey with Alzheimer's disease. They self-published the book in 2005.
