||The Kirkwood estate was centred on Cottlestown House. The name seems to have sometimes been known as Castletown and this is how it appears on the First ed. OS sheet but documentary evidence would seem to suggest the estate was also known as Cottlestown. The Buildings of Ireland survey states that it is likely that the present house was added to an earlier, probably eighteenth century structure, which in turn replaced the fortified house on the site. On modern OS sheets the townland is known as Cottlestown. This property later became part of the Boyd estate.
