I have my Great Great Great Grandfather Daniel Ayres, living in a Caravan on a Public House car-park in Rickmansworth, Hertfordshire in the 1850's. They were working on a Large Family Estate(The Meux Estate) at that time. Then his son Joseph moved his wife and family down to Fifield, nr. Malborough he took up the position of coachman and looked after the horses. This turned out to be another farming area owned by the Meux Estate as in North London. Research has shown that there was part of the family Ayres already living in that area. At the turn of the century the family moved back to the Watford area.
Although caravan dwellers in the 1850's, it appears like all farm labourers they moved arround with the work and working with horses may show a link to the gypsy style of living.
There was also a famous gypsy bare knuckle boxer by the name of Ayres.
If anyone has any connections with my side of the family, I would like to hear from you, so we could exchange research.
