There have not been many updates since around 2002 to this thread. I was wondering if any findings had been made to the original Dunno's. Again.. I am Kyle Dunno son of Jerry Dunno originally from Columbus, OH area. I am currently finishing my master's degree at Clemson University (Clemson, SC). I married a little over two years ago, and we are trying to find some information on the origins of the name. Any progress that has been made would be very helpful. Hope that all are doing well and if you happen to come across this thread drop me a line at kddunno@clemson.edu to update me with any information. I look forward to hearing from you.
