Do you have any information as to who Fredericks father was?
My gg-grandfather was Benjamin F. Patterson born about 1820 in SC. I believe that Frederick may have been an older brother to my Benjamin with Abner Patterson (b. abt. 1770 in NC) being their father. This is unproven at this time but with the proximity of their households, number of children in the various census records,and the names given to the children, I feel it is a strong possibility. Looking forward to any additional info you may have.
