So in the first Pirates of the Caribbean, The Curse of the Black Pearl, when Jack Sparrow first arrives at the port, the man asks him for a schilling and his name in order to "tie up his boat" in the dock. Jack Sparrow gives him 3 schillings instead in hopes for remaining nameless. As Jack Sparrow walks away, the man calls him "Mr. Smith".
Also, later when he is talking to the two guards at the boat, just before Elizabeth Swan falls from the ledge into the water, the guards ask him his name and he replies "Smith".
Is there any significance in this in the fact that he is referenced to as and references himself as Smith, since the first mate that he recruits for his quest is Arabella Smith, the daughter of the infamous pirate Laura Smith? Or is this just a mere coincidence?
