The lands of Elliston, previously Elliotston[1] or Eliotstoun[2] or Elliestoun[3] in the Parish of Lochwinnoch were part of the holdings of the Barony of Elliston, later a part of the Castle Semple barony and estates. The ruins of the castle lie a short distance from Howwood in Renfrewshire in a private garden on a minor road between the A737 and the B776. The name may have derived from earlier holders of the lands, however the Sempill family held them since at least 1220. The castle was abandoned circa 1550 when John Sempill, 1st Lord Sempill moved to a new castle at Castleton which he renamed Castle Semple (NS 377602).[1]
