I'm not sure if you are still interested but my wife's family is significantly connected to the Suman's in Dayton, Ohio. I also have information about the old family farm in East Dayton the includes Suman, Kester, and Gummer Ave. Many streets were named after family members. My wife is a Kester. Finally there is reference to a Sgt. Peter Suman serving in the Revolutionary War. Is this the same Peter Suman?
