Joann apparently was in bad health only for a short time. She was at the New England Regional Genealogical Conference (NERGC), held a few weeks ago in Springfield, Massachusetts. Click on her picture to see larger image. That photo was taken a few weeks ago at the NERGC conference. She apparently became ill sometime after that conference.
