The Nagles originally inhabited the castle at Ballynamona but later built a house adjoining the castle. Garret Nagle was resident in 1814 and Lewis refers to Ballynamona as the ancient family residence "about to be rebuilt". Garret Nagle occupied a house at Ballynamona valued at £9.15 shillings at the time of Griffith's Valuation which he held from John Furlong. The house is still occupied.
