of 1654 based on Timothy Pont's earlier map gives 'Reuinskraig on the west side of the Clerkland Burn and 'Corshill' on the east side. Both are depicted the same without any clear suggestion of 'Reuinskraig' being a ruin. The 1779 estate map of Lainshaw shows Corsehill as a relatively small and apparently intact property on the east bank of the Corsehill/Clerkland Burn, reached by a road branching off at Cocklebie, running across the top of what is now the Cunninghame-Watt Park and turning uphill to reach the house. An avenue of trees ran down to the town, however this was interrupted by some of the Cocklebie lands which are not shown planted up. The ruined castle is shown as just the surviving part of the tower and it is otherwise unnamed. The whole area is called the Corsehill lands. Surprisingly only ten years after the estate map was surveyed Grose shows Corsehill House as an abandoned and much robbed ruin. The 1828 map of Ayrshire by William Johnson only records Corsehill lying on the east side of the burn. The 1776 map by Taylor & Skinner shows a 'Corsehill' only as a dwelling house held by Sir William Cunynhame (sic). The old Corsehill Castle and Corsehill House (NS 416 415) were separate entities and a vague memory may persist of Templehouse and its fortalice at Darlington on the lands of Corsehill Farm, causing some extra confusion. (see below) Many references can be found to Corsehill/Corshill or even Crosshill in old records, none for 'Ravenscraig', but several for 'Reuincraig', although as stated, this is just a description of a ruin that was called 'Corsehill', 'ruined Corsehill'. Archibald Adamson in his 'Rambles Round Kilmarnock' of 1875 makes no mention of the name Ravenscraig, calling the site he visited Corsehill. Aitken only marks Crosshill Castle in 1829 on the west side of the Corsehill Burn. The first OS maps show only the surviving castle's site. To sum up, the map in Pont's 'Cuninghame' of 1604–1608 shows two buildings, "Reuincraige" and "Corshill", at approximately NS 417 467 and NS 422 465 respectively, and Dobie comments that the two have often been confused, but that "Reuincraig" stood on the west side of the Corsehill Burn and "Corsehill Mansion" on its east. "Reuincraig", he says, was ".. so modernised about 1840 that it was difficult to realise that it had been ruined in 1608", while the
