Irdu and Hindi as I understand it are very closely related Indo-European languages. In fact, like Serbo-Croat they can be seen as essentially the same language, but divided by politics,and by two different ways of writing them.

The thing about this is that there are different groups of people who for various reasons have taken to the travelling life in different parts of the world. There've been the diaspora of the Roma from India over the past thousand years or so. The Pavee in Ireland have a different origin.

Every now and again other peopelhave been driven onto the roads - famine refugees, refugees from war, refugees from slums. And there have been people who have seen this way of life as better than the alternative open to them. The New Age Travellers were just one of the more recent examples of this process.

To some extent the common life and problems have led to mingling and and intermarriage, and sharing of cultures.

There isn't really a term to cover all these people. Travelling people is better than most - travelling does not define them, because often enough they aren't travelling. If they are it may because they are forced to; and if they are settled it may be because they are forced to. The form the persecution takes varies.

So whatever term you use, you use with courtesy, and with the willingness to use whatever term the people concerned prefer. I've found that where I live the term "gypsy traveller" tends to be preferred, because there has been so much hate stirred up against "New Age" travellers. But I'm sure it varies.

Incidentally I found when I looked it up a bit ago that "bloke" is a word from the Shelta language. It's good to think one of our most common words comes from there. (I know, I know, the Americans don't seem to use it. But I think most other English speaking people do.)
