I have no familiarity with the show at all. I just guessed common names. I got 6 - John, Jack, Charlie, Charles, Alex(andra), and Sawyer. I forget which common name it accepted for 'Sawyer', but I certainly didn't guess 'Sawyer'. Was it Luke?
According to the quiz, there is a character named Sawyer Ford. In actuality, the character of James Ford was better known by the alias "Sawyer," which was not even a first name, but the last name of the man who conned his parents when he was a child, resulting in disastrous consequences. Either way, his real name was James Ford, and though later in the series he called himself Jim LaFleur, he was best known simply as "Sawyer," never Sawyer Ford.

I agree! They are appeared in more episodes and were more relevant than many others in the list. And more importantly, they belong to the first seasons when Lost was still a good show.
