An interesting study about the Irish Tinkers or Travellers. According to the genetic study, while they are from Irish origins (i.e. not related to Rroma at all), they separated from the general Irish population much earlier than thought, around the late 16th century. This long time as a separate population makes them genetically distinct from nowadays’ Irish.
