Thomas Rawson, in his 1807
Statistical Survey of the County of Kildare, assessed the trees planted on the estate: At Harristown, near Kilcullen, that very great improver John La Touche,
Esq. has formed within a few years most magnificent and extensive plantations; he has adopted very much the plan of grouping each kind by itself, which prevents their injuring each other, as they invariably do, when planted promiscuously; in group plantations, if executed with taste, you have an immediate dotted carpet of various hues. John David La Touche died in 1810, His son John, who succeeded him, He died in 1822. which was closed down by the presiding La Touche owing to the fact that he "thought that the Irish were too industrious". It was not specified which La Touche had supposedly been involved in these acts. John "The Master" La Touche (1814–1904) inherited the house in 1844 and lived there for the next 62 years alongside his wife, the novelist
Maria Catherine Price La Touche. Maria La Touche wrote two novels, "
The Clintons" (1853), and "
Lady Willoughby" (1855), both published in London. She was adverse to
blood sports, and often complained about the neighbouring gentry who engaged in
fox hunting. Rose became the object of the "crazed infatuation" of writer
John Ruskin, though his offers of marriage were refused. The family had met Ruskin in London in 1858. During the
Great Irish Famine (1845-1852), John was sympathetic to the suffering of his tenants, "allowing no white bread or pastry to be made, and only the simplest dishes to appear on his table. The deer-park at Harristown ceased at this time to have any deer in it; all were made into food for the starving people." Around 1870, La Touche initiated
Bible studying classes in Harristown House, which became the start of a local
Baptist church group, who later convened in Rose Cottage, Brannockstown, named after John's youngest daughter. He also started becoming involved in
Christian relief projects in London, raising money to support "
fallen women", and was instrumental in the founding of the
London City Mission. According to Richard Blayney, the
pastor of Brannockstown Baptist Church in 2021, "there is a lingering question of whether tenants and employees of the Master of Harristown were expected to attend the (religious) services in Brannockstown. In the years since then, some have even maintained that regular attendance of the Baptist church was a condition of employment at Harristown". As of 2021, the church was still in use, drawing regular attendees from as far as 40 kilometres away. puts the date at 1864. A railway station was opened at Harristown, although it was much closer to the site of the ruined Harristown Castle than to Harristown House. A dedicated
station master (and family) lived onsite at Harristown station. The increasing
popularity of the motorcar at the time meant that ultimately passenger numbers on the route began to decline, and the last regular passenger service was withdrawn in January 1947. The line eventually closed completely in 1959. It was under John La Touche's direction that the majority of the remains of Portlester Castle (aka Harristown Castle) were knocked down in 1884 in order to build a
national school from the rubble at Brannockstown, which opened in 1885. The school survived for twenty years, but under his son, Percy, the pupils moved to the national school at Carnalway. ==1891 fire==
