If you go to the link that Bruno so kindly shared with us at nearly the beginning of this thread you can download a very informative tome that kind of indicates what it's like to be a "traveller" in Great Britain. They aren't all Roms (who don't speak English as their first language) there are some who apparently are just as british (or Scottish) as everyone else.
They are harassed and discriminated against all over (the world) different parts of Great Britain have slightly different attitudes towards them, in some places they are chased out of town immediately, in others, they are permitted to stay on private property designated for them. There are all kinds of social services apparently ready to help with their children's health and education. It's the same old story; they're different, so they are hated.
When I saw the article that started this thread, I had no idea that they were anything except normal people from great britain, because the code words "Caravan" and "Traveller" do not have the same significance for me, a citizen of the US of A.
I thank everyone for adding to my education. I still think the mother of the bride is inappropriate. but that's my opinion. (Looks like the mother of the groom agrees with me!!)
