"That is the heart of it - that people will not have to be torn away from their familiar surroundings," says Ms Martha Honiball (81), explaining the source of her differences with the McGraths.
"That really does destroy old people."
To her, the availability of a nursing home service in Clonmannon is central to the whole idea of the place. A major part of its attraction was that people living in the "village" could, if they became ill or incapacitated, go to the nursing home in Clonmannon House itself and remain close to partners and friends.
As she put it in an open letter to the McGraths and other interested parties: "This is what all of us came here for and are now being asked to disclaim, with nothing concrete being offered in its place."
Originally the nursing home was in Clonmannon House, the mansion around which the village was planned. It also housed a social centre, oratory and other facilities. But the nursing home and house were closed to residents by the previous owners at the start of 1994, two years before the McGraths bought Clonmannon.
The McGraths immediately made it clear to residents that they intended to live in Clonmannon House and that they had "absolutely no intention of providing any residential nursing facility for the foreseeable future as, very simply, there are too many other matters which require our immediate attention and cash investment".
Martha Honiball believes the McGraths got their priorities wrong. "Rather than spending the money they spent fixing up the basement - that was an awful waste of money - they could have set up some small nursing arrangement here," she says. (The basement was refurbished as a social centre and dining area for residents of the retirement bungalows.)
"Would it have been impossible for them to plan some sort of a small community centre and nursing home with a loan?"
She does not accept that the McGraths need Clonmannon House as a residence. "There's a variety of houses here that they could have made into some kind of a residence for themselves. They're a young couple, active and energetic; why do they have to live in the grandeur of a mansion. Why didn't they fix a house up?"
She told the McGraths in a letter: "Clonmannon House is the hub, centre, nucleus, - the very heart - of our retirement village, to be used for the variety of needs of the elderly living here; i.e. meals, laundry, nursing care, social gathering, etc. It is not meant to be a private residence."
She and her husband invested their life savings to buy into Clonmannon in 1990. When he died in 1993 it was, she says, "with the certain knowledge of my security in Clonmannon Village".
Resident Mr Liam Furlong also left the McGraths in no doubt where he stood in a letter which stated: "The access to and use of the club house is inherent to my contractual arrangements in Clonmannon. In fact, the use of the club house is an extension of my bungalow".
Martha Honiball believes a solution is possible if the McGraths are prepared to build a community centre with a medical and nursing facility on the grounds of Clonmannon. (Jane McGrath would not tell The Irish Times whether the future developments at which she hinted would include a medical or nursing facility on the grounds.)
In a stern reply to the open letter from Martha Honiball, mentioned above, Jane and Roddy McGrath wrote that "we are shocked at your continued insulting and derogatory attack on us and our family" and that "luckily for us your opinion is not shared by 90 per cent of owners".
Of Jane McGrath's suggestion that those who do not like how things are done at Clonmannon move out, Ms Honiball says: "Where can I move? There's no place in Ireland that I can go - except a nursing home where I'd be paying £350, £400 a week."
