AL Haynes, from Lingfield Close, contacted the Gazette to object to plans by Terrance and Kathleen Lowther to site caravans on land at the end of Heatherleazes.
The letter said: "The fact that the Lowthers are claiming to be travellers is, or should be, irrelevant. The family have already been refused planning permission to build a bungalow on the site, or to carry out commercial activities there. They have now chosen to play the traveller card in an attempt to gain special status as part of a carefully orchestrated campaign."
Although the land has been passed down to the Lowthers through Kathleen's family, their plans have met a tidal wave of objections from villagers.
AGC Wilson, of Heatherleazes, called the proposal for up to three caravans "visually intrusive" and went on, "The application stresses the rights of minorities. Jimmy Miller, who with his wife Evelyn owned the bungalow at 11 Heatherleazes adjacent to the site, gave his life in the Second World War defending the rights and freedom of minorities.
"It is ironic that the legacy to their children, grandchildren and great grandchildren should be greatly diminished by this development."
Philip Hope, also of Heatherleazes, claims that since the Lowthers arrival, traffic on the entrance track to the road has "increased dramatically", putting children and ramblers at risk.
But the family say they have no choice but to set up home in Warkworth after their traveller camp in Carlisle was closed down and other local sites are full.
Their youngest daughter Lisa Anne, 23, is battling cancer. She is living in a caravan next to her parents while receiving three months of radiotherapy at Newcastle General Hospital for a malignant lymphoma.
Councillors will discuss the application on June 26.
