Just came across this today. Susan (nee Higgins) Erwin was my great-grandmother. She is buried in a cemetary just outside of La Grange, Wisconsin, next to her husband and two of their children. I have visited this cemetary and have pictures of the headstones.

Also, the daughter, Mrs. Schroeder, from Blair, WI, is Mrs. Paul Schroeder. Her husband was a minister, and officiated at the services.
