Harriet Whiton Storrs was my 2nd Great Grandmother. She is a real person. I have been doing a lot of family research the past 5 years, but do not have any more information than you do on Harriet. I would be very interested in obtaining a picture(s) of the quilt, if you still have it, to put in my family info.
She had two additional children (from the 2 you mentioned) Harriet Grace and Arthur Hovey. A. H. Storrs was my great grandfather. He grew up in Scranton, PA and also had a residence in Waverly, PA where I lived.
