one Hugh Lamberton, a merchant of Glasgow, left £300 in the early 19th century as the Lamberton Mortification to be used to provide fuel, food or clothing for the local poor. He may have come from Townhead of Lambroughton, as he was obviously a man with strong local connections. A marriage stone built into a wall on the farm reads 'AL MR 1707'. This may be Alexander Langmuir; however, it predates the ownership of the farm by his father Gabriel Longmuir in 1734. Another stone bears a date which seems to be 1724 and was part of a two-story building demolished in 2006. Reid's Family History gives the occupants, but not necessarily the owners, with Alexander Langmuir in 1532, John in 1603, Alexander in 1609 and his first wife Isabel (nee Langmure) and daughter Isabel. His second wife was Janet Tod. In 1666 we have Alexander Langmure, John Langmuir in 1710, Alexander in 1721, John Langmuir in 1730 and Gabriel Langmuir in 1730, who as stated below, was an owner occupier. Alexander Langmuir was living there in 1762 and in 1794 Alexander Longmuir was referred to in papers held in the Scottish National Archives as a 'Portioner' of Lambroughton. The records of Dreghorn Parish church give these dates as the family tradition was to become church elders. Samuelle Moors of Lambroughtoune purchased lands in Chapletoune from John Faulds of Kingswell Muir in 1709, with Thomas Brown as the tenant. An Adam Moor had been a previous occupant. Townhead of Lambroughton (Lambrochtoune) itself must have passed to the Longmuirs by 1734 as it is recorded by McNaught that Gabriel Longmuir of what is now High Langmuir owned the farm at this date. In 1811–1813, Alexander Longmuir held the property, his wife being Margaret Roid (Reid). In 1820, Robertson gives Lambertonhead a rental value of £118, the proprietor being William Orr, Esq. As stated, Lambrouchton-head was owned in 1734 by Gabriel Longmuir who was succeeded by Alexander Longmuir, whose sister, Margaret, married William Orr in Langmuir, Kilmaurs. Their eldest son William Orr succeeded to the property in 1808 and built the present mansion house. William married Grizell Lock of Hollybush in Paisley and had eight sons and two daughters. The eldest son, Alexander inherited the property in 1856 and married Margaret Gilmour of Dunlop. They had seven children who inherited the property conjointly. Alexander Orr Esquire of Lambroughton Mains died on 5
