Arthur H. Griffith was leasing this property from the King-Harman estate at the time of Griffiths Valuation in the early 1850s, when it was valued at almost £41. The house shown on the 1st edition Ordnance survey map is labelled Longfield House. The expanded range of buildings at the site, shown on the 25-inch map of the early 20th century, is labelled Gortmore House. O'Brien writes that Arthur Hill Griffith built this house c.1840 but that the Griffith family moved to Australia in 1871. He also notes that the previous house, known as Longfield, had been occupied by members of the Langstaff family. In 1837 Lewis referred to Longfield as the seat of J. Langstaff. Gortmore is no longer extant.
