The term Traveller and Gypsy are used as one by non-travellers here in England, along with pike. As Nick will tell you, Travellers are usually thought of as Irish and Gypsies are the real deal , i.e Romany Gypsies.

There are terms such as mumper, which is a term going out of usage, for people who have drifted into a nomadic life.

Trust me if you have it in your blood or you have close contact as Nick does then there are alot more names of different groups - both Rom and Gadjo and ends up very confusing to try and explain!!
