no it's pointless
Wheel of Fortune does not give the last names of contestants like Jeopardy
On May 20 2011 Jeopardy had a biblical forgiveness category and the questions and answers and also the contestants responses are available on the related link The category was part of the double Jeopardy round and will be found in the second round of categories for the day.
They had 11 Brandon who were contestants and none had the last name close to Carney in a search of the Jeopardy Archive. I also could find no players with the name Carney. I have added a link to the site under related links if you want to check other spellings.
By checking the question history, we see that this question was posed on October 17, 2009, so the episode in question aired on October 16, 2009. Final Jeopardy! for Friday, October 16, 2009 (Winner: Kevin Wilson - $31199) Category: Scientific Firsts Answer: The first object in our solar system discovered by telescope was not a planet but one of these. Question: What is a moon? (referring to Galileo's discovery of one of Jupiter's moons)

There are no unused questions on Jeopardy. There are questions that the contestants could not answer because they tried and failed and others that they didn't even try. Both types of questions are called a triple stumper and the answers are available at the Jeopardy Archive for that date (see related link) Questions that were never presented because they ran out of time are unknown and we would never know if they are saved and to used in a different puzzle, but it seems unlikely. When you see the Team Jacob Category for January 18 2011 The first 3 Questions were Triple Stumpers and the last two were not called upon.
