I'm also looking for information on a Clemmons. I have 2 different spellings on this last name though. Clemmons and Clemons. Mary "Polly" Clemmons married Alexander Ferguson June 26, 1827 in Sangamon County. Mary was born in Menard Co. abt 1805 and died in Mason Co. aft 1880. I know you don't have much info on your Clemmens but I thought maybe you could see something I have that can be useful to you and then likewise you have something I can use. If you don't see anything just let me know.
