Pinckney is said by some to have first name, "James," while others give him middle initial, "W."  I haven't seen any primary records with either.

The name being misspelled here is the surname, "Pinckney," used as a given name.  Charles PINCKNEY (1757-1824) and his second cousin, Charles Cotesworth PINCKNEY (1746-1825), were signers of the U.S. Constitution as delegates from South Carolina.  In addition to those who held the name through a blood connection, many a child in the South was given the name, Pinckney, presumably in their honor.  Pinkney and Pickney would be misspellings.

She is said to be Sarah GILPIN-WILSON, but which is her maiden name and which is her prior husband's name?

Sometimes an enumerator will actually get it right.
