The Irish Times remarked in 1999:

"Mount Irwin, outside the village of Tynan and some 10 miles from Armagh city, was for many centuries the home of the Irwin family. In 1977, the property was bought by Frank King from the last member of the family, Joyce Irwin, who died in the early 1980s." 

"Mr King sold Mount Irwin last June and is now disposing of its contents. The earliest parts of the house date from around 1690 but it has been much altered since with a major extension added about 100 years ago."
