In parts of Spain there are still groups of 'Quinquis'. (Pronounced just like 'kinky' in English)
Quinquis were traditonally rag and bone merchants - who would sharpen your knives, fix your pots and steal your boots from your feet as you walked- a kind of Spanish tinker, if you will. As many other travelling peoples they had a terrible reputation, and the English word kinky may come from this source.
All quinqui menfolk had a combination of three names, Jose, Martin and Ramon. For any individual one of the above would serve as a given name, while the other two were surnames. This was supposedly a means of confounding the authorities. Within their own communities there was no problem- the names were for official purposes only, and every individual would also have an often hereditary nickname by which they would be universally known.
