- Sir Thomas Ross held almost 300 acres in the parish of Lissonuffy, barony and county of Roscommon, at the time of Griffith's Valuation. It would appear that he bought the 246 acres of Ashbrook from the sale of the estate of Eleanor O'Ferrall in July 1850. George Kelly was the main tenant of Sir Thomas Ross. In the 1870s Sir Thomas Ross of Castletown, county Carlow, owned 445 acres in county Roscommon. The estate of Allen Theophilus Ross, Thomas French Ross and John Innes Bathe, in the parishes of Lissonuffy and Killukin, barony of Roscommon, was advertised for sale in April 1879. It included premises in county Dublin.
