My favorite quiz show is "Jeopardy." On "Jeopardy," sometimes they phrase their clues in such a way that, even though the contestant may not know the answer, they can take an educated guess.
When I composed question # 28, I was thinking along the lines of giving people a chance to take a guess. My thinking was that people might figure that, well, there was a lot of fighting around Culp's Hill, and if somebody named Culp had a hill, maybe he had a farm, too, and that might lead them to guess "Culp" as the correct answer.
Of course, if someone is taking a guess on the last name, there is very little chance that they would guess the first name of Wesley. So, to give the guessers a chance, I asked only for the last name.
And I didn't want to penalize anybody who knew that the last name was Culp but guessed wrong on the first name, so I specified that people could give me both first and last name if they wanted to, but they'd better be careful, because if they gave me the wrong first name, I'd have to mark the answer incorrect.
My source said the soldier's name was Wesley Culp, and all but one of those who gave me a first name also said Wesley Culp.
As you pointed out, John B. said it was John Wesley Culp, but he included a source backing his answer. I will normally give credit for any answer for which the player cites a source, unless I can verify that the source doesn't say what the player thought it did.
John B. indicated that his source was Pfanz' book on Gettysburg. Not only did he indicate which book was his source, he even cited the page numbers.
I don't happen to have a copy of that book, but I'm not conscientious enough to go running out to the bookstore to buy myself a copy in order to verify one player's response. I'm trusting John B. on this one.
Sockknitter sent me a link to an interesting article indicating that Wesley Culp may actually have been killed on his uncle's land, rather than his father's, but my source said he was killed on his father's land, so I accepted all responses that gave Culp as the answer to question # 28.
Sockknitter's article also includes an interesting story about a message Wesley Culp may have been bearing for a resident of the town.
Here's Sockknitter's link to the article.
