Susan, I am from Duff & my family name is Whisitt. I do not have all the info on Col. McDuff who founded Duff, Indiana but I do have a book which has more info. If you would like to e-mail me directly I will look it all up & respond. We are having a family reunion for the Whitsitt's on Aug. 30, 2003 in Holland, IN, (approx. 5 mi. form Duff). If interested please email me.
