Where is Ketzah on a map of the middle east?

Although the city of Capernaum really did exist, there are no references to Ketzah on maps for first century Judea. Capernaum is situated on the north shore of the Sea of Galilee, and given the fact that long distance travel was problematic, it would be logical to assume that the fictional village of Ketzah was nearby. A topographical map of the area would give some possible locations, given the description of the landscape, but not the exact location.
