Lisman is a hamlet in Webster County, once much bigger than it is now. My family were early settlers in the area. It is centered around the old Shiloh Cumberland Presbyterian Church, and the town was originally called Shiloh. When the post office was established in the late 1870s, it was obvious there were too many places called Shiloh already. The suggestion was to name it Rice, after my family. However, there already was a Riceland, KY and they thought it would be confusing. Thus they picked the name of the first postmaster, who happened to be Noah Lisman (I think).
The Lismans are another early family in the area and have intermarried with mine. They go back to Peter Lismann, who came from the Palatinate (Pfalz) in western Germany, landing in Philadelphia in 1785. Peter Lisman and his family were in Jefferson Co., KY by 1800. Peter's son John (Johann) was born in VA about 1795 and is the one who started the Lismans in Henderson, Hopkins and Webster Co. region of western KY.
There are other Lismans who came to America about the same time as Peter and are believed to be close relatives. As I recall, they went to Indiana and then further west. The family name is not common, so it shouldn't be all that hard to track them down.
