Also located at Duntryleague are the remains of a Protestant church tower and a graveyard. A number of the graves are occupied by the Bennett family, who had owned nearby Gleneffy House Estate (also known as Castle Creagh) from the 1680s until the 1920s. William H Massy Bennett, a Justice of the Peace, was the last Bennett to live there. He died in 1920 and it was sold by his son George Latham Massy Bennett in an auction in July 1920. In 1826 the Rev P Fitzgerald referred to Castle Creagh as "a very handsome seat of the Bennet family, now in ruins" in his History of Limerick. The current Gleneffy House was built for William's father, George Latham Bennett by the architect Charles Frederick Anderson in the 1850s, it stands on the site of the older castle, mentioned by the Rev Fitzgerald, and is located on the hillside of the Glen of Aherlow to the north of Galbally. It is now a private residence.
