about 1765 or 1770. Lillias Porterfield married William Somerville of Kennox. Their youngest child, a daughter, married Colonel McAlester, Laird of Loup, in Kintyre. A descendant built Chapelton House near Stewarton. Hapland is near Dunlop. In 1820 the estate was of and the proprietor was Lieutenant-General Alexander Trotter. The old mansion house was demolished around 1876 as it was not in keeping with the modern age. A new steading was built at the site, possibly the 'Newhouse' marked on the OS maps. Some of the old tree wind-breaks and policies of the estate can still be made out. It seems likely that Temple-Ryburn had its name changed to Hapland at around this time as the OS of 1858 shows Ryburn in the same position as later maps (1897, etc.) show Hapland. Mains Quarry The Mains Quarry siding lay between Dunlop and the Gameshill road overbridge on the old G&SWR double track line running towards Stewarton. It was a single siding running parallel to the main line towards the road overbridge. The processed whinstone stone was carried to the siding by a narrow gauge tramway, raised for approximately half its length on a narrow embankment running for a total of just over 1000 ft (305m) from the Mains Quarry buildings. The quarry and its tramway lay to the west of the main line between the farms of South Netherhouses and Mains of Aiket. Quarrying had already taken place at Mains since at least 1856 and thus prior to the 1871 opening of the G&SWR line. The quarry's narrow gauge line is recorded as a tramway on the 1909–1910 25-inch-to-the-mile OS map, by which time it appears to have already become disused as no infrastructure is shown where it reaches the siding, although the standard gauge private siding itself is still shown running down towards the road overbridge at that date. A section of lifted track and trackbed may be represented by dotted lines on the map, lying parallel to the private siding. It is not obvious how the stone was transferred however it is clear that the narrow gauge line lay some height above the private siding at the point where they met. A signal post is shown to the south of this siding's point work and what may have been a ground frame stands nearby. The tramway line curved tightly away from the main line and then ran westwards in
