The dates look about right, and the son, James W. Jones, died in 1852. However, the middle initial for James is wrong, and you know nothing about a daughter. In all three cases, the researcher is confounded, confused, and sidetracked in the research. But there are two crucial points here. First, information gleaned from public records of any sort is not protected under copyright law when someone copies it down onto a standard genealogy chart or enters it into a database.
Vital records are public records.
Court records are public records. Facts gleaned from tombstone inscriptions are public records. A wealth of other sources can provide the researcher with facts that also are public records. Second, copyright law does not protect the data content of anything published. Data can be acquired, compiled, justified, and cited.
