Anita, thank you for checking on this. I was 99% certain she never lived in Poe, Ohio, but I hesitated to go to 100%. You just never know on some things. We have a forum member, Cyndy Irvine, who discovered a trip Mary made that I am pretty certain is not in any Mary Lincoln book I own. I do believe it's a new discovery, and Cyndy posted about it here. Cyndy's published article is online here.
