Im another person who worked with many travellers or gypsy families. The travelling community has suffered from negative stereotypes which are not confirmed when you get to know families and individuals. There is a hierarch, similar to the class culture in wider society, with Irish tinkers firmly at the lower end and circus or fair travellers elevated.
As Monica says, it's very difficult to maintain a traditional traveller lifestyle, not least because roadside stopping places are disappearing. Many areas have a traveller site placed in what was a traditional stopping place. One of the large former mining areas I worked in had a section of the estate housing travelling families. This meant large family groups could live near and support each other. The also shared a trailer and took turns to travel for several weeks at a time.
NanyandG, the local primary school accepted some traveller children would start their long summer holiday in June rather than July.
Education is valued much more now than even thirty years ago. The importance of numeracy and literacy is acknowledged. Many parents went to literacy and numeracy classes set up firb hem at local schools so they weren't left behind and could help their children, as Anya said, there is a tendency for teenagers to leave school at 14, boys into work, girls being prepared to be wives and mothers.
Cultural identity, religious faith, care of children the elderly and love of family remain central to life even if travelling in the traditional way is no,longer possible
