In 1786 Wilson refers to Kilcooley as the residence of Sir William Barker. This was the seat of the Barker and later Ponsonby Barker family in the 18th and 19th centuries. It remained in the possession of the family now known as Ponsonby until the early 21st century. The present house dates from the late 18th century, the family having previously lived in the old abbey. The house was partially destroyed by a fire in 1839 and rebuilt. In the mid 19th century the house was valued at £67.10 shillings. It was sold in 2004 and offered for sale again in 2015.
