Oghill House was completed in 1839 by Robert Armstrong. Around 1920 the house and almost 20 acres of land was purchased by the Parish of Kilglass, as a parochial house, for £550 by Canon William Healy. The staff in Oghill Parochial House came to four; two housekeepers and two farm labourers. Canon Malone sold Oghill House and land to John Wall in 1963. It is now the home of P.J. and Gail Wall and their family.

Robert Armstrong's father was the local magistrate and he sat at the courthouse in Easky. Rumour has it that Robert Armstrong Senior was known as "Hanging Judge Armstrong" as he was supposed to hang people off Easky Bridge. Robert Armstrong Senior lived in what is now John Walls barn and out houses. Robert Armstrong Junior left Oghill House to his two nieces, the O'Malley's. Not much is known about the sisters other than they kept horses. They were run off the land in the late 1800's during the land uprising. From then to the time the church bought the land, facts are few. There is a large garden but over the years a lot of trees have died and there are only a few left including a pear tree that doesn't bear fruit.

Two men, who cycled from the Ballina area every day, for one shilling a week, built the house. The house is symmetrical in shape - if it was cut in half, each half would be identical. It has six rooms upstairs and four rooms downstairs with a large reception hall. In recent years the house has been refurbished and plumbing has been added together with a bathroom. The wiring in the house has been replaced.

The outside walls are two foot thick and it has nineteen windows. At the back of the house the old servant quarters are still standing, although in bad repair. It has been said that Oghill House is haunted.
