Travelers is actually an old term for Irish and Scottish itinerants that live like the Rom or Gypsies. We have some groups of them in this country centered in the Carolinas. St. Petersburg Florida used to get infestations of them every few years that got newspaper headlines of “The Terrible Williamsons Are Here” due to most of that particular group being of the Williamson clan. The Travelers do mostly fast scams like tarring driveways and renewing roofs with waste motor oil and such and don’t get into the “romantic” Gypsy stuff like Tarot so much. They steal everything they can pick up.
Don’t they also betroth their youngsters at an early age in creepy ceremonies? I seem to remember a 60 Minutes story about these people. Con men and thieves with a strange social system.
