Marc

Form of Marcus. Saint Marc was the author of the second Gospel in the New Testament. He is the patron saint of Venice, where he is supposedly buried. Though in use during the Middle Ages, Marc was not common in the English-speaking world until the 19th century, when it began to be used alongside the classical form Marcus.

In the Celtic legend of Tristan and Yseult, this was the name of a King of Cornwall. It was also borne by the American author Marc Twain (1835-1910), real name Samuel Clemens, the author of 'Tom Sawyer' and 'Huckleberry Finn'. He actually took his pen name from a call used by riverboat workers on the Mississippi River to indicate a depth of two fathoms. This is also the usual English spelling of the name of the 1st-century BC Roman triumvir Marcus Antonius (Marc Antony).
