Carol,
Wyant Lepper applied for and received a Congressional pension based on his military service, #S-10980. His first name was spelled in variants such as Weigand, Wygand, Wiand, Wyand . . .
By now you probably know that you can look at and copy the material in the pension application files at major libraries, or send to the National Archives for a copy of the full file.
This man was among the sons of Conrad Lepper. You can look at a summary of the family at
