John James was, but so far, I haven't found anything on the father. There are several Turrentines listed, includeing a John R. Turrentine, but one the grave stone,
the name is listed as John (no middle initial) Turrentine. This may be faulty reasoning, but if his business partner, H.H. Higgins, born in 1802, was involved, then
Turrentine, born in 1811, might have been. Just trying to follow all possible leads. Thanks.
