Weir writes that this was originally a McAdam property. Ballyglass was described as a steward's house at the time of Griffith's Valuation and was held by Andrew Caswell in fee. It was valued at £10. Modernised in the Tudor style in the early 20th century the house is still inhabited. It was valued at £25 in 1906 and was then in the possession of Mark Maunsell. Also known as Rosmadda House.
