Mark

"And your name?" she said, "I suppose it's quite unremarkable?" "Very funny." "Mark. It could stand as a symbol of a man, for men as a category," she reflected, "but I don't suppose that's why your mother gave it to you?" "My mother's motives always were impenetrable to me. I was her only child, she wanted a simple life. So she gave me a simple name to go along with it. --- It wasn't a popular name until the nineteenth century. People were put off by King Mark in the Tristram and Iseult."

, Acts 15: 37-39:

And Barnabas was determined to take with them John, whose surname was Mark. But Paul thought it not good to take him with them, who departed from them in Pamphylia, and went not with them to the work. And the contention was so sharp between them, that they departed asunder from the other; and so Barnabas took Mark, and sailed to Cyprus.
