My 3rd Great-Greatfather was Richard Mendenhall (1852-1924). He lived in Allen, Darke, Ohio starting in the 1900 U.S. Census record.

On Wikipedia, Allen Township is described as vastly wide, flat farmland- which makes sense because a lot of my ancestors were farmers. In 2000, the population was 1,158 people. The town was first organized in March 1839. Doing some research online, there isn't much to see in this town.
