At the time of Griffith's Valuation Hugh O'Beirne was occupying a house at Jamestown, barony of Leitrm, valued at £40. Jamestown House was held by the O'Beirne family until the twentieth century though in 1894 Slater refers to it as the seat of Gilbert King, junior. In 1906 it was also valued at £40. It is still extant and occupied.
