Over here (UK), Gypsies are Romany; Travellers and Tinkers are also (or used to be) nomadic, but have usually been here longer and are usually not Rom (others will disagree about that, particularly as "Travellers" has in recent years become used as a catch-all term for nomadic families regardless of their backgrounds).  "New Age" travellers are what used to be called "drop-outs", and are not related to the traditional travelling groups in any way, except perhaps by aspiration.
