Yes, I took the picture of her grave that is on her profile. She is in the "Sedgwick Pie." If you would like a picture of Catharine's grave, or any other, I can make a trip to Stockbridge for you. (I could not find Norman Rockwell's grave, but it is there, too.) I think there is a dog in The Sedgwick Pie.
Important: she is not the first freed slave. Her case abolished slavery in the state.
