The Haughey family have stated that former Taoiseach Charles Haughey never entertained former British prime minister Margaret Thatcher or former Libyan leader Muammar Gaddafi at Abbeville.
The family were responding to a report carried on RTÉ News last night that stated the two were among a number of guests entertained by Charles Haughey over the years.
In a statement the family said: "We wish to state that neither of these people were ever in Abbeville.
"We are concerned that people may believe that Colonel Gaddafi in particular was a guest of Mr Haughey and are very anxious to have this matter clarified."
Auctioneering company Savills Ireland has apologised for stating in their sales brochure that Gaddafi and Ms Thatcher stayed in Abbeville.
The claim had been included in a sales brochure for the mansion and estate, which is back on the market with an asking price of €7.5m.
In a brief statement, they said they had understood their original information was correct but based on what the Haughey family are saying Savills has reviewed the wording in their sales brochure and made appropriate amendments.
The spokesperson said they apologised for any confusion caused.
A spokesperson for the Department of Foreign Affairs has told RTÉ they have no records of Gaddafi ever having visited this country in an official capacity.
The spokesperson said they had checked their records here and with the Irish embassy in Rome.
