The Campbell family held an estate at Mount Campbell outside Drumsna since the early eighteenth century. Lt. Col. Josias Campbell served as High Sheriff of Leitrim in 1720 and his son Samuel held the same office in 1756. In 1766 the Campbell estate passed to the Rowley family through marriage. The Campbells were also related to the Southwell and Russell families, Barons de Clifford.
